Like the car, but a suggestion, these cars breath fairly heavy through the kidney grills, I'd move the driving lights as far as possible to allow air flow. Might even do a light blister to get them onto the hood...
Of course it depends on how sustained your revs are,,, Have FUN!

Sounds like a lot of work (or does that just reflect my apathy towards projects like this after all of these years ) Good luck though...........should be epic when it's done.
