Ahh, thanks guys. And, thanks for the pics! The arm and leg assembly would probably be out for the moment. Spending way to much on this truck and more to come. I do like the parts wanted ad idea.
My current thinking goes like this. I'm gonna treat this like a couch that gets bolted to the floor. I'll make up 4 steel "legs" and bolt them down, then look for mechanism to properly rebuild the assembly to install at some point in the future.
Klhansen. Thanks for the measurement offer. I may take you up on that. The passenger side of my seat has the sheet metal cover intact, so I'm planning on taking the measurements from that side.
