Hi all The gearbox in the mid 90's M900/900SS engine I'm rebuilding has some chips out of the sixth gear on the input side. Part No. 17210052A superseded by 17210053A. It's used in M900, 900SS and 916 gearboxes and probably others too. The 748 is 17210052C but I don't know what the difference between the C and A is. Anyway, does anyone have a broken gearbox with this cog undamaged that they'd like to sell. Thanks Nasher.
