Are the doors interchangeable from the targa to the hardtop? I have an 89 hardtop and the passenger door is rusted badly, I have spotted a passenger door from an 88 targa. Will the door just bolt on and be ready to do?? If there are differences, what are they? Thanks.

I wouldn't see why you would have a problem with it, might want to get a person who knows those cars better than I do though.

Yes the doors are interchangable, just remove the "stud" on the targa door to make it fit.

What is the "stud"?

If you have a targa door you will know what it is, it's a silver peice above the door lock that sticks out 1" or so.
