Nice project truck! Welcome to the forum. Hand crank nut is 1 3/4". https://www.handhwiring.com/cloth-wiring https://www.ledlight.com/ledlight-6-volt-positive-chassis-catalog.aspx I know a guy that works on gauge clusters and speedometers.

I believe so. The guy that bought has a '71 R/T Hemi Challenger too.

Just read your signature. Sold it about 7 years ago. GT clone.

Welcome. X's 2 on the pics!

Ya, trucks before '52 are non-synchro. I found one is a yard in Susanville and bolted it in. Nice not to double clutch all the time. Kinda wish I'd kept the truck. LOL

Welcome. Is it a San Leandro or Los Angeles truck? A tranny from a '52 or newer is a bolt in and is synchronized from the 2nd to 3rd and 3rd to 4th shifts.

I wish someone would make a decal with a 3/4 passenger side shot WC, then a B1-2 front, then a B3-4 front and lastly a C series 3/4 drivers side shot. I'd buy a few.

Might want to try this guy: https://www.rsgaugeworks.com/index.html

What's wrong with the stock speedo?

X's 2.

They say $40 shipping? https://dcmclassics.com/bed-parts/279-bp-199-78-5-steel-bed-strips-78-39-53.html#/year-1939_1947

There's an arm between the bourbon tube and needle that can be bent. Set your air compressor at 60lbs, use a rubber tipped blow off tool and adjust the gauge until it reads accordingly.

The old gauge is adjustable.
