Well, that's quite the hacked out crossmember. Big ol' ****** too! Clark 5 speed?Doesn't look like a regular Borg Warner T-9 crash box, and those should bolt right into a half ton with no mods, just a different bolt on mount. I have a column shift 3 speed here that you can have. It looks pretty rough on the outside, but who knows? My wife's sister lives in Ellensburg and she's heading over the pass in a couple of weeks to visit her. I could toss the ****** in the back of her subaru. She is easy with that type of stuff. Does the truck run? V8 or six? I can get a pic or two of the trans and post it up. Mac VanPelt here on the forum is a wealth of knowledge and parts for a rebuild. Truck looks to be in excellent condition and I'm gonna speculate it's from the Right side of Oregon.
