Borg Warner 9 bolt

Would some one point me to some places that sell ring and pinion gear sets for this rear end. Thx!! Might be a good sticky to make on where to purchase gears for our factroy installed rear ends.

Have you done a search? There is a specific company called something like
"9 bolt".

I'm still running my factory 9 bolt with 3.70 gears.

I've also seen the 3.70 ratio for sale at Reider Racing. That's the only ratio I've seen for sale and very few places carry them. Finding parts for a nine bolt is not an easy task.
