Zip,

looks like a great product. I just used lithium grease. I know it wil harden but I'll keep after it. In 3-5 years, I'll disassemble and relube the bits.

See if you can find a can of this stuff:

My neighbor used it on the shift linkage for an old 1 ton GMC truck he rebuilt about ten years ago.... It was still there last year when he tore things apart again.

Comes out of the can like cheeze-whiz.... doesn't taste so good though.
And, it's a multi-tasker. You can use it as a dielectric grease.

What grease should be used with the clutch pivot arm ball and pin?

I assume just anything would work, but it seems wheel bearing grease would attract a bit of dirt. There was a post on a clutch issue where some suggestions were made, but I cannot find it via search...
