I have a 12 bolt out of I believe a 1972 chevy truck. I have a lot of slop and found the spider gears on the center pin moving like a disco.

Question-- Will a carrier from any other 12 bolt be the same?

Just like others with these money pits, I am trying to save a buck when I can. I found a few at some wrecking yards for way way less then a new one and they are tight.

Thanks in advance
