TR3: Pump Cam for A-type Overdrive

["Musson, Carl" <musson@satie.arts.usf.edu>]

The first of the gremlins has sprung its nasty head on my recent
purchase.  (Actually it was the second - the first was that the
"completely" rebuilt engine did not have a rear main seal  - go
figure...  That one was easily remedied.)

Trying to locate:

Pump Cam for A-type Overdrive
Part No. 500627

Or same with pump assembly (no part number available)

Thanks.
