pilot bearing size?

[SVOJames]

I'm replacing the Spec Stage 2 clutch setup I installed about 6 years ago with the same setup, and the pilot bearing that was included with SF722 was slightly smaller in circumference, slightly shorter in length. It did not appear to have the O-Ring in front (gearbox side).
My plastic micrometer is worthless here, I've had the clutch set way to long to return it, I'm just wanting to get the right part this time.
Thanks in advance!

Go to a parts store and get the proper bearing. ~$10/US, iirc. I may have one somewhere in the shop. Iirc I will get a Ford PN this evening. You have a puller? I got one of those too.
