QUESTION FOR UCA BALL JOINT SEPARATION

As to the tapers I cannot say, But If a bushing exists,I imagine yes. IDK, cuz I dont mess with front ends.

What I mean by that is I don't mess with factory engineering.I figure those guys are waaaay smarter than me, and their designs were meant to keep people alive, and I ain't messing with that!
-But yeah, they didn't put near enough caster into our As, but I know how to change that! Unfortunately cranking the caster up to 4or5 degrees is not without it's own problems.But they too, are not insurmountable.
-There doesn't seem to be a good reason tho, to have changed from the small-pins to the larger, unless it was maybe bearing material longevity, inside. But even that IDK, cuz both joints go about the same distance.And,I've never heard of any small-pin BJ coming apart. Further,I have not treated mine kindly; no autocrossing, but I jumped the car a few times,and hammer over speedbumps, and they say Manitoba has some of the worst roads in Canada, and I can't argue that cuz I have hammered through some pretty ugly potholes!,so IDK.
-I think maybe the small-pinners were a compromise,cuz you gotta remember that they were still putting 13" rims on these cars until the mid 60s. I wonder if a 13 with the correct pattern and bs would clear that badboy big-pinner?
-I put a 15x8 custom rally steel wheel small BP,on that KH set-up, and I had cranked a lot of bs (I no longer recall the measurement;4.25maybe),into it to put the scrub radius about where the factory had it. That was a bit of a chore. When the suspension drooped to the limit of the shock, the BJ and the wheel wanted to occupy the same space! It took a bit of grinding here and there to make it all work, and the wheel weights needed to be relocated.....I still have those WheelVintiques,only run one summer.
