I have up for sale a Centerforce Dual Friction clutch 10.5 inch with 10 spline input. I had it in my 88LX and its only got 500 miles on it.
I can email pics to anyone interested
$150 plus the ride
I see that the coupes rotors are 10.75 in and the gt's are 11.25. So thats a quarter inch on each side. I might be able to section the brackets down but swapping axles is out . I have a Detroit Tru Trac with 31 spline Strange forged axles and c-clip eliminators not to mention 2 sets of wheels...
I would do it if I didnt have to drill new holes in my hatch. I think it would look pretty nasty from the rear matched up with the tank sump, my drag radials and the turn downs.....
