I am wanting a good 3.21 gear set from a Corporate 14 bolt FF. Must be willing to ship or close enough to NW Indiana for me to come and pick up. Would consider a whole rear end if the price is right.

Have you found a gear set/rear yet? I have an '80 14-bolt ff complete rear. Thanks, Bob.

No I haven't found one yet. Any chance of selling me just the carrier and drop out the front pinion and housing? I could image shipping a whole rear would be quite costly from FL to Indiana

Is this to replace the 4.56's in your extended cab? Just curious here, why 3.21's specifically? I would think a 3.73 or 3.42 ratio would be in the mix also. Might have better luck with broader expectations.

3.42's would be fine, just shooting for the highest gear available if I am to choose.
