Well, just wanted to return to this topic to let y'all know what we've found out. We started tearing down the axles to restore them. The combat rims, although dirty and paint chipping, are in dang good shape! No major damage or rust. The axle had a repezza (SP?) joint on one side, and it looks like someone might have blown up the ball and claw that was in there, and then replaced it with the repezza. The other side still had the ball and claw, and was in great condition! Found no water or rust inside the brake drums, knuckles, or axle housings.
I am still looking at the possibility of using the rims for my project, but if for some reason I cant, NDT gets first dibs on the sale.
Thank you all!
