Just to keep you posted (and Karl reliving his nightmares) I have yet to remove the right rear Axle nut on Walter... I tried a large Monkey wrench, a tube extender, and a chisel and a BF hammer... I am now going to get a Dremel cut in it and start weakening it until it snaps...
Yes, I bought a new one before i started messing with this one. I found a nut and bolt site in the same street as my favorite junkyard/parts place that even had them in their catalog. M24 castle nut for VWs, said in their price list. US$4.
Side question, can I upgrade the front axle nuts to the newer ones with an allen screw? I cant find the plates you a re supposed to replace....
