First off, KEEP THE RAG JOINT if you can. Otherwise you'll feel every pebble in the road in your fingers, and if you bump a curb, it'll jerk the wheel out of your hands. As far as hooking it up to your steering box, use steering universal joints. Look in the catalog from Classic performance Products. They have the right components to hook it up correctly and safely. I had the same problem with a 52 Ford cab on a Chevy S-10 frame with a Cadillac steering column. Originally, the column went through the floor at the frame, and I had to route my new column through the firewall. I called CPP, gave them the information, and they sent me the correct pieces for a quick bolt on. $69 for the joint, $19 for the shaft. It's a lot easier than trying to piece it together from junk yard parts.
