7-1/4 rear market

all i really need is the carrier and 16-17 inches of the axleshafts from the spline side i modify them to fit other applications in tractor transaxles
so hub pattern is not an issue what would those three pcs weigh together roughly for shipping

If that's all you're wanting check your local junkyards for M-body 5th Ave's. Check for slant and 318 powered F-bodies, too.

Check over on FMJ's to see if anyone near you might have one. Same as here: just about everyone has done an upgrade.
