Yesterday was finally the day I located a posi for my C20. I've only been looking for a few years now!!! Found one in a junkyard. First I saw G86 no spin rear on the glove label, then investigated further.

Once I confirmed it was a posi, I just yanked the center section out. Gear oil was fairly clean with no metal particles. Wear pattern on teeth look great!

The best part.....I paid $31.75 for it at a local pick n pull!

Now the only thing is I don't know what the gear ratio is yet. Hoping it's a 4.10 and if so, I can use it and simply bolt it right in. Truck had a 350 and the big 4 speed so probably a 4.10 (pray).
