My god, that car is beautiful! I’m sure there is someone out there that knows more about it than I, but my memory tells me convertibles had a different frame configuration than the hard tops. (For lack of overhead rigidity). I’m guessing the convertible frame rails are bigger than the hard tops, but it’s been 45 years since I’ve been under either of them.Can anyone tell me if the 1967 oldsmobile Delmont 88 2 door convertible rear frame rails can be cut and put on my 1968 Oldsmobile Delmont 88 2 door hardtop. Are the frames the same ??? Please help thank you john View attachment 163
