    Hey guy's I have been searching for a Dana 60 or Corp 14 bolt rear axle for a 68 GMC swb fleet side that I am building and came across a complete AAM 1150 out of a 2005 Chevy 2500 Duramax and wanted to see if anyone has installed one of these in a 67-72 gm truck, Blazer or Jimmy. I can't find any specs on this axle so I don't know what the spring pad widths and axle to axle flange width is.
    Any info or suggestions? Thanks.

    I don't have the 11.5, but I did pick up a 07 10.5 that I'll be putting in mine. I havent exactly studied to much about it to make sure everything bolts up but for 100 bucks I wasnt leaving it behind.

    I searched and saw that a few threads are showing them to be 68.5 from WMS to WMS. Perches should be 48 7/8.

    They use 14mm lug studs. Should be very close to just shy of 70" wms. Very stout axle but I'm not a fan personally of the differential inside. I much prefer the dodge torsen style if I had a choice. I dont think theres anything smaller than a 1410 pinion yoke.
    It essentially requires everything done to it to fit.
