Thanks guys! That is good to know about the 45 mph. I have driven these trucks before. It has been awhile. We had a 1939 on our wheat farm that we used to haul wheat every year and for sure it would go 45 especially going down hill with a full load!! lol The steering would develop a vicious death wobble but she got the job done. My wife and I had a 1939 Plymouth pickup that we had a lot of fun in for several years. 45 mph was about it for her too and she did the wiggle wobble too. After I look it over, I’ll try again. I was so excited maybe I was doing something stupid like shifting from third back down to second instead of fourth. Sounded like I was upshifting but.... I plan on looking at those levers very carefully. Also I found the laylock 2-speed on here which sounds like a good plan. Thanks again. I’ll keep you posted.
