REPEAT MISTAKE: NEVER LEAVE A PART AT A GARAGE FOR LATER-LCA ISSUE

@RustyRatRod thanks for the input
These LCA's are in the original condition since removed and boxed up-say 1985, not even cleaned. Both of the LCA inner swivel were loose and rotating freely.
The right one in picture #2 at arrow looks bent when compared to the left one and is thinner in thickness measuring across all three plates, little over 1/8".
When I grab and twist the TB socket the inner swivel will lock up after around 15* spin then it tightens up that I almost need a pipe wrench to rotate it more. it jams up about 3 times in its range of motion. I don't think they used the 2"x 6" pipe that I supplied to level the arm for the pressing operation. If they placed the arm on the press without the pipe it would rest on the slanted section of the LCA.
pressing the tap out through the hex socket with a larger pin than the one I also supplied would have essentially pressed all three pieces together and tightened everything up. At least that's my best-case scenario I can come up with.
If used as-is, I believe it would be rubbing/grinding together, however slightly, when driven on the road. [rebound and jounce motion] I couldn't knowingly use it as it was.
