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.....
Thats funny you said that. My gt40 plenum's vacuum tree pierced my drivers side valve cover about 15 years ago.
Anyway, just get a gasket kit from Summit or Jegs or wherever you like and do it once and be done with it.
Depending on how long it was out, there could be a good amount back there. Although it really shouldnt be dripping on your exhaust. Valve covers tight?
