hello all, new buick guy to the forum. I have a 1940 model 46s coupe. building a taildragger, lowered, fender skirts, 4" chop, keeping the straight 8 with dual carbs, you get the picture. I would like to know if I can use a later buick 15" wheel to replace the 16" wheels that are stock? what year did buick switch to 15"? and would they also be a 5 on 5 bolt pattern? thanks, Jeff
