Well done. Love the gauge treatment. If the old tranny wont hold up to all of that power, Limeworks makes a neat column which looks like a 3-on-the-tree. We used one on my son's '51 truck and we are really pleased with how it turned out.
Seems to be holding up just fine. I dont beat on it. I just drive it around like a normal everyday truck. I have a fast car if i want to beat on something. I plan to swap to a slightly newer mid 50’s full syncro 3 speed with a Borg Warner overdrive this winter. Will still be able to keep the 3 on the tree .
