As I see it everything you have described is within class, but I'll get an inspector to give the official view.

5.D.2.a Altered Coupe - page 56
This class encompasses American coupe or sedan bodies 1982 to the current year, and foreign coupe or sedan bodies 1928 to the current year, unaltered in height, width, length or contour. The body shall be mounted to the chassis with all body panels mounted in the original relationship to each other. One of the following modifications shall be done to be considered in this class:
1. The addition of a step pan as defined in Section 4.EE.
2. The engine set back a maximum of 25% of the wheelbase as defined in Section 4.AA.
3. A front-wheel drive vehicle converted to rear wheel drive.
4. Covered headlights and grille as described below.

Any frame may be used as long as the bottom line of the frame is not higher than the outer bottom line of the body between the firewall and the rear wheels. An exception will be made if a stock frame and the same year/make of body are being used. If the ORIGINAL frame/body relationship is such that the lower bottom line of the frame is above the outer bottom line of the body, that frame/body combination may be used. The burden of proof of the ORIGINAL frame/body relationship lies with the entrant. The frame may not be exposed from the bottom of the body. This rule does NOT apply to Vintage body class vehicles.

This class is allowed a 2% maximum body stretch in the cowl area, in front of the firewall. This does not apply to Vintage class. An engine swap as defined in Section 4.N is permitted.

No streamlining, as described in Section 4.CC is allowed, unless specified. Wheel wells may not be filled or covered. Bumpers, grilles and front lights may be removed and the opening created may be filled or covered. The filled or covered area may be flush with the adjacent body; the basic shape and contour of the vehicle cannot be changed. Engine intake air may be ducted from these openings. Aftermarket front ends are allowed as long as the item conforms to the class guidelines. Any horizontal paneling which may be construed as a belly pan is prohibited. No taped or filled body, door or window seams are allowed from the firewall back. Windows shall be mounted in the stock fashion or fastened to the inside of the window openings. A non-stock spoiler is permitted as defined in Section 4.CC.6. Any type of exhaust may be used and can exit anywhere from the body but the top.

Roof-mounted spoilers, other than original for the body used, are prohibited. Pre-1949 bodies may be chopped. The chop shall be equal front to rear and shall retain a vertical windshield height of at least 6 in. above the top of the cowl with a maximum horizontal length of 7 in. from the base of the windshield at the center of the car. The driver shall sit completely ahead of the rear axle, inside the body, and behind the engine, except in rear-engine cars using the original engine LOCATION. Drip rails may be removed or filled.

Cars in this class are considered in the Modified Category and should comply with the General Rules of the category. Coupes and sedans produced from 1949 to the current model year, not meeting the criteria of the Classic Category, shall compete in the Modified Category classes. Vehicles in this category that exceed 200 MPH, or if the existing record is over 200 MPH, shall have roof rails.
Engine classes allowed are: AA, A, B, C, D, E, F, G, H, I, J, XF, XO, XXF, and XXO

Roof Chop Questions

As quoted in the rules for altered, does this mean even though we are in classic and permitted a 3" beauty chop in Classic altered we can take it down even further leaving just 6"?
5.D.2.a Altered Coupe - page 56
Pre-1949 bodies may be chopped. The chop shall be equal front to rear and shall retain a vertical windshield height of at least 6 in. above the top of the cowl with a maximum horizontal length of 7 in. from the base of the windshield at the center of the car.
The next question i'm wondering. Where do you take the 6" measurement from? If i'm reading it right its the flat part of the cowl where the hood meets about 2 inches lower than the bottom of the glass(green arrow). Or is it from the bottom of the glass (Blue arrow) ?

My next question is about laying the windscreen back. I know i've read somewhere this isn't allowed or (wasn't in the past). However the rules only state the top contour has to be maintained.
4.I CHOPPING:
The reduction of the overall height of a closed top vehicle, where the original general top contour is
maintained. Materials can be added or removed to maintain the original shape. Size and base
positioning of pillars must be in original OEM locations. Category specific requirements must be met
It would change the chopping process quite a bit if i could lay it back and not have to lengthen the roof as much. Anyone know for sure??

Gus,Greg,
Gus, your next lesson with salt lake racing is scrutineers have all interest in safety and compliance. They will pass your car as good to run on safety but will leave class compliance to the competitors own interpretation of the rulebook. You have asked this question before and I cannot give an answer. It confuses me.
You can nominate and run whatever class you desire provided your meet safety requirements at scruitineering. If you set a record its yours and if you are wrong it will still hold unless someone protests you at THAT meeting.
This is a really wrong part of our rule book. ( see C/PRO example.)
I hope in the future as we progress and grow we will have volunteers who profess to specialise in a particular class and be able to advise. I have put my hand up in Utes and Pick /Ups to be it but we have so many classes to find someone that a/. knows the class inside and out and b/ is available and willing. The DLRA is a work in progress.
Landracing.com have a far broader person base as you require the right answer before you commit to such a chop top.
Bob can answer your front question on front runners but he is off line at the moment. Some Frontrunners you can run and some you can't, so again ask on landracing.com if you don't get a timely answer here.
Greg, any one else here we can ask? Clocks ticking and a chop on a Terraplane is a big deal?

Chris, thanks mate, that does lay it out quite simply. If we focus on meeting the safety rules, we'll get to run. That's all that really matters to us. As far as fitting into a class well just do our best. I just like making stuff look cool, and that roof is annoying me a bit. It may have to wait till the following season.

Yes that clock is ticking :?

After reading the http://www.landracing.com forum for half the day im just gonna go with max 3" chop and dont lean the windscreen back at all. No arguments then. I found my exact same question a couple times and couldnt really see any evidence otherwise.

Yes, a lot to read on Landracing but some good info. I think you are right. 3" is the answer.

Bob Ellis has the best roof chop (in my opinion) on his XP Falcon two door coupe. He just cut the C pillar and then raked the windscreen back to suit it. That was when the rules allowed that simple method. Then someone changed the rules so that you couldn't alter the pillar angles, so Big Gaz's Shaguar was built that way. He had to buy another XJS roof panel and go to a hell of a lot of trouble and expense to make it all fit. Then someone realised what a stupid rule it was and changed it back to the easy method.

Read the rules again, it's in there somewhere. Good luck chopping the six pillars and making it all fit nicely. But from what the photos have shown us already I think you guys will get it done pronto.

Cheers
Starter Dave :mrgreen:

This project is a real turn on! You are so lucky to have willing and capable blokes with the enthusiasm to get the job done quick. Mine took eight years. That was eight years of dreams and nightmares.
I am not sure how you can build the cage and do the chop later.
Don't forget the head restraints as these will need to be incorporated into the cage from day one.
Roof chop- it is all in the interpretation of "contour". Keeping the same angle on the front and rear screen should be a lot easier than on the Jag. I admit there is a lot of information on the Shaguar build pages but there was miles more that never made it to print.
Good luck, keep up the good work. Don't forget to check and double check the rule book. Ask questions if you are not 100% sure don't hesitate to pm or call me if you need to.
BIG GAZ.

Well convinced the guys we can do this (none of us have any experience before) and with more confidence on my face than i really have, i started to chop up a perfectly good terraplane body. We spent about 8 hrs on it today and its going well. pictures tell 1000 words
