T5 Five speed slant six 74 Dart Sport.

You can use something like this....

I have used these for ~20 years in 2 slant 6 cars with 10" discs.

They are not a direct fit, as you need to have a machine shop drill your flywheel to fit them on the slant 6.

The clutch fork pivot will also need to be shimmed about 1/2" closer to the engine if you use one of these ford pressure plates.

The I.D. of the pressure ring will not match the disc, but I had no problems with rpms over 6000, or lugging around a heavy '79 volare.
