Those are the wrong shafts. The threads bottomed out. They look almost like E-body pivots, but I’m away from my parts stash at the moment so I can’t comfirm. Needless to say they’re different from A-body pivots.
Bushings in the K-member? There aren’t any. The pivot mounts are just metal tubes welded inside the K frame. If they’re damaged, changing them involves cutting open the K frame, so yeah, PITA. Did you mean the LCA bushings? Cause that’s different.
Mine are from Firm Feel Inc. They get torqued to 100 ft/lbs.
Yup.
The poly bushings had nothing to do with this, so, the rubber bushings won’t solve it. This isn’t a reason not to use the poly bushings and greasable pivots, as long as you get the right pivots. Not sure if PST sent you E-body pivots or if their design is wrong, but that one you broke isn’t right for an A body either way.
As for that rubber bushing, it doesn’t look used but that rubber looks hammered. Like it’s deteriorated or UV damaged. I wouldn’t use it.
