Hi Brian. May be interested in the ring & pinion. Would you have a posi unit, or possibly a posi 8.5" 10-bolt rear axle with 3.08, 2.73, or 2.56 gears? Thanks, Anthony

I have a posi unit to go with it,or I can build a whole rear.
$350.00 for the gears and posi.
$1100.00 for a complete 3:08 posi rear.
Where are you located?

Looking for posi and gears for a 10 bolts as well for my '71 Supreme . It will end up behind a 200r4. Pushing about 360 hp on the rebuilt 350 .

If you are running an overdrive,I would run something in the 3:73-3:90 range.

Thanks Brian for the advice. I was originally thinking that, but thought it might be too steep. It will be a huge change off the line considering I'm running stock 2.73's right now.
