BDI Express carries a couple options and can be ordered online. I've used them in the past and their service has been terrific.

Hi Eldert,
I'm in Long Beach CA.
Chino has changed a lot. Used to be dairy farms. Now it's housing developments.
Were you racing anything when you were in California? I used to run at Riverside, Ontario, Willow Springs and Sears Point but, obviously, that was a long time ago.

Thanks for the info!
I have not yet disassembled the crank.
It is from a narrow case M1 engine in storage many years. It was knocking badly and has noticable radial play. From research, I think this crank should have a stepped 27-30mm crankpin
(27mm ends in flywheels). But it does not make sense with the 32x39x18 bearing. It seems with a
30mm pin size at the big end and 3.5mm rollers
The bearing should be 30x37x18.
Help me understand!
Dave

Hi Dave
original crankpin is 27 /32 / 27
