OOOOHHHH SS######T

What now any Suggestions?
I thought about cutting an access hole in the subframe with a grinder or torch then weld in a new one but it is kind of an uneven surface and it would be hard to get a welder to fit under the car and in a blind hole to weld a bolt perfectly in place, unless i dropped the hole subframe? SOuds like alot of work
Take Diff out Drill out old hole with larger hole saw - weld bolt to piece of subframe then weld back in the piece i cut out ? I thought this would be the easyest

any other ideas, I didnt see any access holes on the frame so it looks like i am going to have to make my own.
Please help

I think I'm having the same problem...eccept I'm just missing one of the two diff mounting bolts near the drive shaft. I hope mine doesnt break during replacing it, after reading this i'm goanna get me some bolt breaker.

what size bolts/washers are these?
