14 bolts arent that hard to find in the boneyard. Go find one with the same ratio and get the carrier, ring and pinion gears. Get one without gov lock so you don't end up with the same carnage again.

I'd bet you got 3.73's or 4.10's in your 76 k20 axles which are really common ratios for 3/4 ton trucks. shouldn't be too hard to get a used set. If you do it right you shouldn't have too much trouble to set up the gears in your housing. Don't give up and let those parts rot outside yet.
