It’s a 489 with a cone type SG ( Not a posi, I didn’t machine it to fit the GM carrier in it). It appears the pinion has rubbed the carrier at some point in its life.
Do not understand what you are saying..
I would be interested in that flex plate.I assuming it is for a 727 and really could use the convertor bolts as well.
The convertor is working fine and I left feedback for you as well.
PM me.
Thanks,
Martin
