Last fall I bought a roof cut off a 1983 mustang to get the t-top conversion started on my Capri. My Capri has a funky 1980s hack sunroof hole so I had to do something. The Mustang doors were rusty junk... Like worse then I'd ever seen. As such I got the glass only. Now I'm getting ready for the conversion and I need guidance on if the regulator is infact unique to t-top cars?
