torque converter bolts sheared!!! Okay so i'm pulling my tranny to change out my craked flexplate and i sheared off one of the 3 torque converter bolts. i"m still trying to extract it on the bench but i need some replacements. My question is what should i replace them with, just grade 8 hex head bolts work??? what grade are the stock ones?
THANKS

The stock ones are metric. They don't go by grade 8 etc. They have a number like 9.8, the higher the stronger.
Unless they are the allen head type.
You can find replacements in the MotorMite Help section of most auto parts stores.
FWIW I've used grade two (no marking) 3/8 bolts on a th400 converter that used nuts and bolts in a one ton truck. In other words they don't have to be super strong. Grade 8 would be fine, or 9.8 metric.

Just be sure on the length, too long is almost as bad as too short and I doubt the hardware store will have the exact length, so you might need to cut them.
10.9 is a pretty strong bolt, maybe equal to a sae grade 8.
