The 4th gen torque arms are held to the T56 transmissions with three bolts. Two of them pass through the transmission and are held on by nuts on the other side, while the third threads into a blind hole in the aluminum tail housing.
It is a common occurence for this 3rd bolt to back out, eventually falling out, causing the outer torque arm bushing bracket to fall off the car and turn the torque arm into a massive swinging hammer under the car. A common solution to this problem is to ditch the bolt, and throw in a stud with double nuts.
Long story short I lost a bolt and now the (already) beat up hole seems to have only a few good threads left.
It's an M10x1.5 hole, looks like most of the inserts will have me drilling and tapping out a hole as big as M16?
The attached pics show what I'm working with.
Which is the better option, doing an insert, or just going up one size to M12? If insert is the better option, which brand/kind should I go with? I was thinking the following:
