I placed a few more shots below related to this topic.

It's an aluminum "Ram" wheel for a members build here with a "Ram" diaphragm style pressure-plate, 10.5".

The wheel weighs about 15#, the plate about 16#.

You can notice the "pan-head" retaining screws helping to hold the ring gear in place. These are more for a precautionary measure?

(Add) On a side note here I sort of like the fact of using the diaphragm plate, they usually require less pedal pressure making it easier on the linkage!

Thanks, Gary in N.Y.

P.S. There are no inserts (heli-coil or otherwise) in any of the pressure-plate bolts. And the wheel has a multi-pattern for various pressure-plates!
