G'day Mart, I,ve just checked a few of my other flywheels and they are pretty much all the same depth where the four bolts go. No drastic differences. I believe Cadillac512 has the answer. Those raised edges around the springs are almost tight against the small circle. The springs are even a little higher above the clutch disc surface. Opening up the circle would solve the side clearance issue but not the height of the springs to the flywheel bolt clearance. So this clutch disc will go on the shelf and i,ll find one with a bit of depth in the centre. We have a few good vintage parts suppliers here in The Netherlands with up to date stocks.

BTW, this new 10 inch clutch disc was in the same box with a new 10 inch pressure plate in a load of pre-war Ford parts i bought a few years ago. That new pressure plate has no counter-weights on the three arms for the throwout bearing. The pressureplate fits the six bolt holes on the flywheel.
