Hi Craig
Did you get sorted?
I have 3.55 posi gears in my Tremec equipped ‘71. 52k miles from new, play in side yokes.
I’m looking to rebuild my diff/rebuild a donor diff with 3.36 gears
My diff is currency in my car and the gears work just fine as you can see from the video. ( side yokes are worn hence the rebuild)
Anyone who has 3.36 gears please get in touch
Thanks , Aaron 07944 858532
