I assembled a World Models T-34 and used an old spinner i had on hand. Well the spinner broke while doing the final assembling. I have another spinner but it is a different brand (DuBro) and it has an inset on the back of the backing plate. The cowl has already been positioned for the other spinner and the DuBro will hit the cowl if installed normally. Can i put a washer or two behind the backplate to space it more forward so it doesn't hit the cowl? What type of washer material would be the best since there are knurls on both the engine and spinner to tighten onto?
