1962 Studebaker Champ pickup, runs, partially restored

I bought it a few years ago. Did some work on it and cleaned it up. Replaced the brake master cylinder. new spark plugs. I welded in some sheet metal where the floor was rusted out. and ripped out the interior. Reupholstered the seat. and did some general cleaning. I didn't clean the engine compartment though. The grime you see there is old. As far as I know it doesn't leak anything. It starts right up every time. even in the cold weather after not being run for weeks. Has the original in line 6 cylinder engine with oil bath air filter and 3 speed transmission. The other running gear is also stock. accept for the brake master cylinder. It runs and drives real nice. even the electrical works. There is however. a knock in the engine which we have narrowed down to the main bearings on one of the cylinders (see the video to hear it). It would take a small amount of machining to make it smooth. and some new bearings. I cut out some 3-ply plywood that I was going to cover and use for the interior but school got in the way. and I didn't get it all in. I managed to massage out a nice wrinkle in the front passenger fender but there are still a couple more small dents. There is no bondo. just old faded paint. It looks like it could be the original paint job. There is some surface rust here and there. but it's not bad. The video shows the spots in the floor where I fixed the rust holes. For its age. it's in really good condition. I'm only selling it is because I need the money and I don't have the time to work on it anymore. My plan was to drop in a chevy 350 and turn it into a street rod. Here is a youtube video of the truck$3500 oboFeel free to message me with questions.
