Hello,
I have a SBC Chevy manual flywheel that I am trying to mate and purchase a clutch kit that fits and ensure that the 12 inch disc diameter - pressure plate mounting is compatible.
Question: On a 12 inch clutch kit, are the pressure plate mounting hole centers located at 12.63 inches (measured from center hole to center hole across the diameter ) ? Please see attached picture for clarification.
I'm assuming that a 12" clutch disc uses a pressure plate that has these mounting hole dimensions but need to confirm.
The rest of the specifications that I need are: 10 count spline, 1.125 inch diameter shaft.

Thanks, Daryl

This says 12.625 or 12 5/8ths so your measured 12.630 is close enough.

Thank you John for your response. I did find the McCleod website today as well as another from RamClutches. Pressure Plates - RAM Clutches

I ended up ordering a 11 inch McCleod clutch/pressure plate kit.

I was assuming they have standard bolt up patterns. You help was very useful.
Thanks again!!
