If anyone has put a Nova clip in vehicle, I need help: I`m installing one in a 1950 Chev 1/2 shortbox. Without a motor installed, should I make sure the wheels are forward in the wheel well or set back from centerline? I hate to center them then find out that with the weight of the truck + SBC makes them set back to far. If they do need to be set away from centerline , how far? Thanks,Darcy
