Anyone know if there is a difference in the vert top frame on a 88-90 and a 91-93. I want to put a headliner in my 90, can I just go buy one for a 91-93 or do I need to change the frame to make it work? I just bought a new top and haven't put it on yet, I want to put it on soon but if I have to change the frame for a headliner then I need to just grin and bear it and buy stock in duct tape.
