this may sound like a stupid question, but what is that flip top cap from originaly? b-body? if its not a b-body, where would one get a couple? cuz ive only seen b/e-body repops. my cuzin is lookin for a pair of flip top caps for his 87 buick regal as i gave him a couple pieces of dart sport 1/4 panels so he can put one on each side to fill from either or
