Working on a project. I chased the threads on an aluminum bellhousing - seems okay. But I've had some strip out that I thought were good.

Was thinking I could just put some decent quality 1/2-13 (think thats correct) studs in, would help align the tranny and then washer/bolt on the stud. Maybe less chance of stripping the aluminum threads.

Bad idea? No stronger?

I've used longer bolts ran in from the back side to make studs when threads were iffy.

If it's apart now, maybe putting in some Helicoils or Time-Serts would be a good idea.

Not a bad idea at all, IMO. I would verify the threads were sound and helicoil them if needed. I would not install bolts from the backside as they would be impossible to hold onto to keep from spinning after the bell is on the car and you're tightening up the trans.....unless they were Lok-Tited.

I've done this trick of using longer bolts in from the back. I use lock washers and triple nuts so that I can use the outer two nuts as jam nuts for tightening and loosening the bolt.

torque them from inside the bell housing install the trans using a hard flat washer under a grade 8 nylon lock nut ditch the gouging split lock washer that digs into the fragile ears
