I was out looking for a spare tire rim at my local scrap yard, and decided i would have a look around on their axle rack. I noticed a massive 14 bolt, 8 lug, full floater. Then i got my tape measurer out and it has the 66 inch WMS to WMS, which tells me it is out of a truck(van has 69). The axle also has the spring pads on it, so that is great. The guy wants $175 which I would pay. My question is this, is there anyway to tell if it has a gov-lock on it without removing the cover? I spun one drum, and the other one spun in the other direction just by turning the first one(is that right?) So if I take this bad boy home, I'll have to buy new 8 lug rims, make a new driveshaft, and rebuild it with 4.10s, bleed the brakes, take my brake lines off my 12 bolt and transfer them on there, which will cost me a couple bucks. I am hoping one of my buddies who has done a 14 bolt SF 6 lug swap on his '73 K10 will be able to help me, plus he had to weld his spring pads on there, the axle I have already has 'em. Any advice for a first time axle swap would be great.
