That sucks. Hope you didn't pay too much for it.
I must have not seen this thread before. I have a 6 bolt head that I'll sell you. And just to make sure you don't get screwed again. I'll give you a money back guarantee if the machine shop says its warped and not able to be milled. Ask anyone on this board that knows me and they'll tell you that I'm a man of my word. I'm one of the OG's after all.
PM me for details.
