I am building a 04 GTO pro mod/stock.I shorten the frame from a Pro stock Olds but from all pics. I've seen I think I should have lengthen the frontend of the body.The body is still in primer so making changes would be no problem. Also where is everyone getting their wheels and tires from.I am on a budget so machined al. is out. My local slot car track has a wide selection of Reliable Resin scoops so those will be easy. Any help will be greatlly appreciated Thanks, Burke
