Default C3 diff questions

Hi

I have a 76 vette. When my mechanic puts it up on his lift, I seem to have very little play in the in/out movement of the left rear wheel.....but more than an inch of play in the right wheel.

Could it be diif springs....or something else causing the issue?

Also, would a 1980 diff wotk on my 76?


Thanks for any help!

Where is the play, wheel bearing or yoke extending from side of differential.
If differential, the ends of the yokes are worn and the differential has to be removed to repair it.
1980 wont fit.

end wears down until the e-ring groove is gone. then the yoke can go out quite a long way. i think the 75 qnd earlier yokesare better. gary- GTR1999 will probably weigh in. he is the diff guru. connecticut if that is close to you.
