Today I stopped by the local junkyard and found a possible open drive axle for my 54 3100. Actually 2 different axles. One is sitting in the back of I believe about 59 3100 so I am assuming that's the truck it came out of. The other is in a newer truck but I'm not sure what it is exactly. That axle bolts to a triangular frame and uses coil springs. I am thinking it is a 60s 3100. It has some big spring perches I would have to cut off but that's an easy job for the cutting torch. I would for sure go with the 59 axle the problem is its missing the cover and one axle shaft. Also it looks like the pinion hit the spider carrier and left some gouge marks. From what I can tell the 60s axle looks complete and in better shape. I thought the 59 axle would be a bolt in but the spring perches are about 1.5 inches too narrow and they appear to be on the top of the axle, not the bottom the way my torque tube currently is. Anyone have any experience with either of these axle types? They are both the correct width and lug pattern.
