Thanks for the advice all. If I end up getting the car (the guy is kinda slow walking me), I'll post it here and see if any of you are interested in a possible project trade. It's pretty rough, but it's all there.
I've seen people do a hardtop to convertible conversion but I'm curious if anyone has done the reverse.
I've found a rusty 70 convertible that I'd love to save, but I'm really looking for a hardtop project. What do you think?
