Dang. Too bad you already got it apart. I'm doing the very same thing to mine, and just bought a 20 ton press. However, I don't think the jig is actually necessary, but I'm going to try mine without. I was going to offer that I give mine a shot, and if it works, you are more than welcome to it, but since you already have the truck down, I don't think thats going to work.
I'm in Arvada.
