Thanks for any help.

I know there are diaphragms that match the 3 1/8" Long style clutch bolt pattern on your Mercury flywheel. You can try NAPA that used to offer them, or clutch re-builders like Fort Wayne Clutch and South Bend Clutch, and the aftermarket like Centerforce, Mcleod, Ram etc. The other alternatives are having your flywheel drilled for a normal evenly spaced diaphragm bolt pattern or purchasing a new flywheel that has multi patterns pre-drilled.
