OK thanks for replies! my two birds I have had since I was a teenager (30 years ago). I have been in the miltary for past 18 years and they just sat for that entire time. Now I'm back in the states and want to get them back to nice street condition (not show car but driver nice). Still not used to the idea of spending money on them as they were my daily drivers and were dirt cheap to drive and maintain back then I actually don't care if I have the original dual traction bar rear axle if I can find a better one that won't explode on speed shifting (original wasn't a 4 pinion posi, just a norm pos and blew apart). My days of street racing are long gone, just want reliable now. The axle I have now is a 68 one and it axle hops like mad as both shock mounts are on same side of axle, not staggered like a 68 would have had. Would love to get a 12 bolt with nice aftermarket bars really.
