[DeTomaso] Stripped Rear Swaybar Bracket Stud

[Mike Drew]

Larry’s solution is similar to the one I employed working on a car in Europe. Three of his studs were broken, I believe. 

First we cut them flush, then drilled and tapped for same-size bolts (it’s impossible to buy studs there so you have to make them). We had just enough access on the back side to thread nuts onto the bolts. We welded the nuts to the inside of the chassis, then welded the end of the bolts to the nuts. Presto. New stud. 

Oh, except it’s a bolt so it had a head in the way. We cut the heads off, then cleaned the threads with a die. When finished, the resultant studs were indistinguishable from the originals. 

Having access to a welder, and courage, made this repair possible. I can’t think of a good way to fix it without welding on the inside of the box section. 

Come to think of it, if you were desperate you could drill completely through the front and back surfaces of the rear crossmember, then use long bolts which would pass through the swaybar brackets, and through both surfaces of the crossmember, and secure them with ordinary nuts on the back side. No welding required then.
