According to Aaron at Fidanza, the Fidanza flywheel has three different bolt patterns, two for pressure plates with for 5/16" bolts and one for 3/8". The counterbore measurements are as follows:

- 3/8" bolt pattern, depth is .20 and width is .375

- 5/16" bolt pattern, depth is .20 and width is .312. This is the pattern my long style McLeod 360500 uses.

Aaron says these FE flywheel counterbore dimensions would have been derived from the original steel flywheel. I have my original R-code flywheel in the garage and I see absolutely no counterbore.

So I guess I will get the thickness of the McLeod pressure plate at the bolt hole, call ARP and do some math.
