My son Harley and I have been working on his 61 Uni for the last couple of years. We finished welding up all the unnecessary holes in the frame, and boxed in the front of the frame back to the cab mounts. We sandblasted the frame and finished painting it. We have the 312 finished up and got everything running. We were supposed to finish up the body work this summer, but we bought a new shop and house so we can't go any farther untill this winter.......bummer......lol.
Here is a pic of the finished frame and power plant:
