i'd say you are definitely getting a good deal on those axles...
as far as good deals go, [brag] I found a '78ish Dodge SRW Dana 60 front w/ drive flanges and 4.10s at the local JY, buried in a pile of trash, and got it for $150 out the door. I even talked the JY dude down from his initial $200 price. About a month earlier, I managed to track down an Eaton HO52 with a factory No-Spin (detroit locker) from a '66 C/20 in Western PA for $100 from a guy who had parted the truck out. Both need rebuilt and one of 'em needs regeared, but I think I am pretty far ahead of the game. I also got a $20 NP205, and then I got an SM465, slip yoke NP205, adaptor between the 2, and a set of blazer seats for FREE from another guy in W. PA who needed his garage cleaned out. You just gotta be in the right place at the right time, I guess. [/brag]
