certainly can. the roof glass is out of a 92 (bought new.) . I have it in storage as I really DO NOT want to destroy a $1200 piece of glass. mine worked sort of until I stripped it and gave it a good clean. now its much better.
get a good look at your glass panel as well mine was rusted underneath and that was NOT visible from the top
as for pulling the roof assy out- its a full upper interior gut. so A,B,C trims off. roof lining out and s second person to help with the s'roof assy. the thing is a bitch to get out by yourself and balance. once you have it out flip it over and drop 4 bolts out of the glass. glass will come off. realigning it is fun as its a in/out job a few times to get it in the right spot.
whilst you have it out have a good look at the main roof panel. if you see anything remotely like mine - get it fixed. otherwise its a glass out roof off exercise.
one request I do have since you have a s'roof car - where do your drains exit the car? there are 4 of them and they come out in the corners somewhere but I cannot find where.
a BIG thanks to DUH19 for letting me take 'useless' photos of his car. (white GTR)
I was having issues with the rear inner fuel tank bracket location and the actual bracket shape (FAST listed two different ones.) but it turns out that the bracket IS the same as the one I have here and it simply slides to the left one hole. his car helped me work that out
about to do a compression test on the engine - hopefully 150PSI + across all 6.
