Aluminum Powerglide pump ??

[GNeric]

Hello all, it has been a long time (18 years) since I have seen a pump gear setup for Powerglide that had Gerotor type gears installed. Does anyone know if these are like the 904 or are they special made. Been trying to find some and did Google searches with no luck. I havent measure any out since all the powerglide pumps in my garage are trashed and unreliable foe measurements and no 904 type transmissions to be built.
