This  is in conjunction to a rebuild thread that I'm in the process of creating for an 88/89 KM132 manual transmission.

Below are part numbers, actual dimensions, and some other info for the internal transmission bearings.  

Note: Inch measurements were taken using calipers. mm was converted from the actual inch measurements.

THIS INFORMATION WAS COLLABORATED FOR AN 88/89 CONQUEST/STARION KM132 MANUAL TRANSMISSION.  EARLIER MODELS MAY DIFFER.
