Dana 60's are super heavy, a front complete D60 can weigh over 500 lbs... They're half inch wall 3.125 inch diameter tubing on the tubes, 1.40 inch+ thick shafts (can be up to 1.625 available in Dana 70's as an upgrade), and the housing is a huge chunk of iron, and a locker for one of them costs like 600 bucks. Ultimate off road axle before Unimogs or Rockwells, I'd say total over kill for anything but the most hard core drag car. :lol: The rear axle version of the D60 would be lighter without the knuckles and U-joints of the front version and what not but they're still really heavy. I'd try to go with something lighter like a 9 inch or a 8.5 ten bolt, or a 12 bolt. Plus unless you've got an original Mopar Dana 60 from a Hemi car (in which case it's probably worth some dough, I'd sell it and get a 9 inch) it's probably a truck axle, and standard single wheel D60's should be 67inch WMS/WMS and dual wheel can be up to 73 inch WMS to WMS in width. That's at least a good foot or more wider than a G-body axle plus you would have to fabricate the mounts for the 4 link and you'd have to get custom hubs unless you're cool with having a 6 bolt or 8 bolt lug pattern and having to use truck wheels since the full floater axle shafts stick through the rim and are held in from the outside by those 6 (or is it 8 ) bolts.
Probably not worth it... In my opinion.

Yes and no gave me time to do a couple more changes. Cant wait to get it going should be in the 600hp range and yes street driven.dlo253 said:

Some good points. It is already narrowed some, and is 5 lug.
Another question, forgive me if its dumb lol. If I go with like a 12 bolt, ill still be able to run boxed LCAs for g body correct? Pretty sure it shouldn't matter but just checking. And does anybody know of any common swaps to convert an a body rear to disk brakes?
If you just girdle that 7.5 and add good axels you can go a long way on it. Stay off slicks and a transbrake. Also if you find an 8.5 you get the driveshaft with it from the donor car so you don't have to have yours cut down. Its then a drop in.
Oh hell ya! Looks like I got me a rear soon enough, my dad is gonna be tubbing his 55 Pontiac, and doing the whole rear... and he currently has a 10 bolt posi in it right now from an A body. He said when he tubs the 55 I can just have that rear. Stoked. Thought I'd share my happiness. Lol.
