I have a little side line business going on in the way of rebuilding brake and suspension parts, and then putting the parts up for sale on this forum, Craigslist, or other Mopar related internet forums.
When i come across big ball joint upper control arms with shot bushings in them, i always remove them, as a courtesy to my buyer(s), making it easier to sell, with me already doing, performing, all hard, dirty work.
There have been numerous threads posted throughout the years about those collars on the bushings.
They were hit or miss, which cars ever got them, from the get go.
Supposedly on the A body cars they were on some of the 6 cylinder cars, the Rear bushing only, and rumored to be on B & E body high performance models. But who really determined what a high performance model was destined to be.
It was just some Chrysler's engineer in the the suspension division that had a brainy idea, and thought it was something to have installed to justify his wage within the corporation.
I have seen them on the A body cars throughout all the years, as that's what i mainly dabble in, and very few B body cars, they have gone away from showing up in wrecking yards, many, many, years ago, around my area, even for California.
