Hi I restored a 46 a few years back. It was tough finding parts then. Probably more of a challenge now. I sold mine a few years back. They are beautiful trucks. My truck was very close to original. I changed the rearend to a higher ratio (Patricks Kit at the time). I replaced the vacuum wiper motors with electric. It had a 216 that I put in insert bearings instead of poured babbet bearings. I did the interior in black and added a radio in the glove box. I found the truck not too much fun to drive. The reasons are: I'm tall and my eye position was just below the wiper motor valence, I had an original brake system but with the faster rear end stopping could be exciting sometimes. I also had single acting knee shocks which made hitting bumps exciting. The truck would at times jump over 2 inches when I hit bump. If you have any questions happy to help if I can remember. I had many posts back at that time.
