Hey Tim: I had a couple custom steel flywheels and clutch plates/discs made by RAM (to my specifications). I wanted the billet flywheels to be light (24 lbs) -- so they are back-cut and scalloped (see the picture). The set below will finally get installed in my 32 Cab in the coming months.
We discussed the whole diaphragm issue and I had them check their clutch plates.
Some diaphragm manufacturers have fingers that are designed (the ends of them) to deal with this situation . . . but buying off of Rock Auto . . . may not be the best thing!
