066/660 - Aftermarket Cranks, Who has used them?

[Tomo6400]

Any one used the precision tooling cylinders.
OBE (Bill) sells them here in Aust.

They seem to be a nice A.M. cylinder mate I was given a few for testing.

Let me know what you think after testing.
I have only used 1 of their pistons from Bill.
