It's been many years ago but I bought a running '78 1-ton SRW for $750. Overall drivetrain was in decent shape but the body was completely rotted out. Started it up, drove it on the trailer, and hauled it home. Pulled the cab and had the local scrap pickers haul it off to the recycle yard, pulled the front D60 for me, and sold rest of the drivetrain pretty cheap. Probably been searching for a year or more when I came across this deal and it was by the cheapest deal in the long run.
A buddy of mine is constantly buying and selling everything from complete cars and trucks, garden tractors, tires, automotive parts, etc....(makes good many) and always keeps an eye out for D60 front axles. He has probably bought and sold a dozen or more in the last several years including picking up about 5 Dodge kingpin/internal hub versions for $150 each from a local yard. A local company had just scrapped out a bunch of their old trucks and scooped it up right away. Believe he got about $500-$600 for the Dodge axles, around $700 for GM versions, and $800-$900 for Ford high pinion versions here in the Midwest. He wouldn't give them away but wanted to get them flipped within a week or two and he found those were the top of the line prices without sitting on them for months waiting on the right seller.
