will they fit?

I can tell you right now that anything beyond 4 7/8 BS is not going to fit on a car with stock spring location without massive spacers.. now with the b-body rear you might be able to get away with it but not sure...

get a carpenters square and take the wheel off of the car.. measure from the face of the drum to the leaf spring.. its like 5 inches.

speaking of spacers, does anyone use the bolt on ones that are > 1 inch thick?
