Built a rear axle dolly this morning using parts from a P.O.S. engine stand and a trampoline frame. Had been soaking the greasy areas over the last couple of days. Got the axle up on the dolly and pressure washed off what I could. Have similar markings that others have found. Intersting though that the black paint I can find looks like it was painted from the top down (see Pic 10a and 11a). Don't see any paint on the case and found fresh cast iron under the sludge (see Pic 1). May have to soak on this some but assume at this point that the case will be painted cast iron gray, the axle tubes black, and will try to replicate the various markings. So far I see green, blue, yellow, pink, and white. Axle marking says A-49 with the posi stamp.
