Ive had my crossmember spot welded in for the past few years. Im pulling my trans out this weekend, im wondering what the bolt and thread size is so I can replace one bolt thats missing and heli coil the holes that are stripped out. Anyone know these sizes?

ttt

The bolts are metric - M10 x 1.5 x 32. I had one strip out, but instead of using a helicoil, I tapped the stripped hole using a 7/16-14 tap (slightly larger than the M10), then used a standard bolt.

I did the exact same thing

i tapped mine to 1/2 inch corse thread and it works great
