Well, I took the plunge! And a razor saw to my Nascar COT body. After a lot of planning then cutting, I have the semblance of what I want. For now it is just taped together and I still have to finish trimming the wheel-wells. It turns out that while it was 2.25" across at the front, back and along the bottom edge, the tops of the wheel-wells are more like 2.5. The two middle sections of the car will need a thin strip cut out to make the whole thing legal, but I can keep the front and rear uncut.
This picture shows the body as it is right now, taped together, and sitting on the chassis of my Sprite build. I wanted it to have at least 2.5 wheelbase and I think it will be 2.75 or more when finished. The body is about 4.25 long as it is now. I still want to trim a little off the bottom to give it a really slammed look. I'll give updated photos as I go along.
There is a plus and a minus to the last option. Plus , you don't have to recreate all the open wheel bits, fenders and headlights etc. Minus , you still have the Scaley guide flag system. Now if you run a chassis up to the front with a new guide-flag, move the motor back, and can still incorporate the plastic bits, then you've got it! maybe I'll try that for SLOP 4.
Post #66 shows the COT cut and pasted. Now I have finished the shell and am ready to paint. I sanded off most of the paint and all of the decals. There were a few uneven points that needed a bit more work. I used Testors plastic model glue to join it back together and also to fill in a few booboos. I had a piece of black plastic window screening and I laid it along the joints on the inside. I was a bit worried that it wasn't going to set hard enough, but it just needed time to harden up. The shape is pretty much there now, and I have started on a brass chassis for it. I have an NSR long can motor on a Slot.it pod and will use the extra front end from my Racer Sideways Capri. The interior has been cut up and just needs a flat sheet of plastic to mount the upper part of the driver, wrap-around head-rest, roll cage pieces etc. In post # 62 you talked about finalizing the rules. Please don't do anything drastic so my car is illegal. That would be very frustrating after all the work so far. I assumed the rules to be the same as this year.
