Hey. I just bought a 48 or 49 6400 on ebay. What an adventure. It runs but needs brake work. When I pulled the rear drum I found that the surface for the axle oil seal was damaged. It looks like someone may have welded on it, then ground it down. Not pretty! I have tried the local places around Tulsa for a repair sleeve. No luck. Surely someone else has had this problem. Also the data plate is missing. I bought the truck on bill of sale with no no title. Any ideas?
