For the clutch disc, there's a Peugeot V6 disc that is the correct diameter and spline count, but trying to find one in NA is next to impossible. I ended up using an Escort ZX2 flywheel, pressure plate and bearing, which is closer in size to the Fuego disc, but there's still about a 1/8" of the disc that overhangs the flywheel center depression.
I had chatted with a local clutch guru about swapping the Renault center into the Ford disc but for some reason it was a no go. He suggested a mating Toyota discs as the small spline Toyota clutches supposedly have a spline count that matches the Renault input shaft, and the larger discs can be made to work with the small spline hub. But, don't quote me on this, I never did pick up the Toyota bits to compare.
Another option would be to get an older Escort flywheel and redrill for the Renault clutch, but the Escort flywheel lacks the 36-1 notches on the backside.
