Factory posi diffs

What ratios were available? I recently saw an ad for a gbody 2.73 posi rear. Did they actually come this tall in a posi? I have my doubts, but hope I'm wrong.

Yes they did. Any ratio that was available was also available as a posi. I've even had a 2.29 posi I pulled from an 84 Grand Prix. I've also come across later 307 cutlasses that had a 2.14 posi, yes 2.14 ratio. Talk about a slug of a gear.

2.14? Wow. Probably couldn't spin ONE tire, let alone both.

Pair that with an S10 T5 and your 267 coulda been Montanabahn contender...

This is great news. I need one.

T5s fix everything. I promise
