2nd gen 12 bolt, 60.75" axle flange to axle flange, 55.25" tube flange to tube flange. Weld on the axle perches (I can do that to your specs if needed) and you're ready to go. I was going to cut this down for my 68, but went Qlink housing instead. Gotta go soon fellas- I'm heading out on another paid desert vacation courtesy of Uncle Sam.
I can also get you the Moser torino ends installed (properly on a jig)with accompanying axles for an additional $550 (and I'll take off $150 from the price 'cuz I'll keep the RR&P axles in it now). Ask Steve68 about how his 12 bolt came out.
Complete assembly is rebuilt using the following:
New bearings & seals throughout
New Motive 3.42 Gears
Rebuilt Eaton Posi w/upgraded clutches
New Summit aluminum cover, with preloads.
New GM spring perches, NOT welded on yet.
New Moroso Yoke straps
New RR&P axles w/ studs (the axles pictured were used for measurements)
$850 obo + shipping (can be freighted for as little as $80 to some places)
