[Denny]

The holes are known for stripping out. The threads are cut into the frame.

Back in the day we used to slide a nut, inside the frame channel over the hole and install the bolt.

I belive they are 3/8-16  if you welded them just try tapping them out see if they hold, if not do the nut thing in the frame.

Are you talking about the front lower control arm hole, where the long 3/8" bolt attaches with the bushings & sleeve?

yes

That’s just a 3/8 hole. The sway bar link has a bushing on each side. Bolt, washer, bushing, a arm, bushing, washer, sleeve, washer, bushing, sway bar, bushing, washer and the nut. Now that I think on it, it could be 5/16. Check the size of the long bolt the came in the link kit.
