Exhaust vs power-steering

Centerforce, 10.5", and "yes" I'll have it balanced with flywheel. 2,300lb. car, should help-a little.:blah5:

I have the centerforce pressure plate too but I mean the disk. Has to fit the splines of the R154 input shaft. I'm wondering that there is only vendor on the market who makes them with 10.5" OD
