So I went to the local speed shop K&S Auto, and the racer there Mike set me up. You can swedge ( 5 lb mallet) a Dorman .462 knurl stud into a .450" hole
I would never have thought. But I done it> Bang Bang Maxwell's silver hammer.
I was with Billy 100% until I done did it. When Mike put the .462' Doemans into the hole you could tell they wanted to be there. one 5 lb mallet and heavy vise for flange support was all she took.
but the lesson here is, when you pound the snot out of your 1967 12 bolt, you best pull her apart and check stuff. I did last year before the MJ467 arrived, But I never pulled the pin. So the moral of the story is, a 12 bolt is like a contra-hand grenade. If you DO NOT want it to grenade, PULL THE PIN for inspection.
because as I halfway re-inserted the pin after C -clipping my repaired axle in , it slipped out, ( gear oil bath all over my hands at that point) and this little guy somehow magically appeared.... and we definitely have a loose spider gear. Diff is out for service!
PULL THE PIN FOR A COMPLETE INSPECTION!!!!! Drop the clips and back out the axles to check your spiders. And their washers!
This would have fragged old Red's original and lazer-straight beautiful sheet metal if the axle unassed itself. OY VEY! Got lucky.
