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.

I am not sure either but they should be since it is not a unibody car. You will need to take careful measurements to know for sure though. It also matters where you will be replacing from as not all areas are as critical. Say for instance behind the rear suspension just to replace damage from a accident. If it is from in front of the suspension mounts then it is very important to get right or the car can dog leg down the road.
