[Model51]

My 1935 was converted at some point into a fire engine and if yours is anything like mine was, there is a rat's nest of wiring, some original in poor shape and lots of splices and added wires. Your truck is so original, I recommend replacing the wiring with good quality original type wiring. You can purchase good quality original color cloth wire harnesses from several suppliers. One is Tyree Harris in Virginia but there are others. It's not too hard to replace the harnesses. There's one for under the dash which includes some that go through the firewall. You can also replace the spark plug wires with original type wires. One source is Third Gen in Tennessee. You may have good parts vendors on the West Coast, I'm most familiar with the East Coast folks, but it really doesn't matter where they are as long as you are getting good quality parts.

Good luck with your truck and keep the posts and pictures coming.
