I have some convertible top assemblies that I want to sell. One is off a 1967 Oldsmobile 88, this assembly will fit a 1965 thru 1970 B & C/ 88 & 98 Olds. The question will this assembly also fit the "larger" Buicks? Next question, I have an top assembly from a 1975 Delta Royale 88, is it interchangeable with the full size Buicks? Thanks, Ken
