I just joined up, live in Grand Junction CO. I have been a guest for a while now and learning from all you folks, very interesting and helpful people on this forum. I don't know where or how to reg. my cat, but it's a 1964 Thiokol 1201, 170 Ford eng. OC-4 (I think) but in it's drop boxes, they are gear not chain. I bought it a few years ago and its been sitting in my shop. It came to me with 1000 hrs and a full length cab which was added at some time. The serial number is (84). Going to get it riding tuff for this years El Nino. I live 2 miles from the Grand Mesa which I can run the cat down the road (rural) and start climbing and having fun. Let me know if I was not supposed to write all this info on this reply. I new, so just give me a kick and redirect me. Thankyou
