I do not have an original Truck. The last Truck I built was powered by a Honda clone, and I did not build it to original specs, as at the time I did not have them. That said, I did have a factory measurement for the box, and estimated the rest from there. I no longer have that truck, but I bet I was within an inch or two in most respects.
For this build, I asked Vince for some measurements from his beautiful original 1952 Truck, which he graciously provided. Thanks again Vince!
I started with a 1954 bike frame, and have fabricated the rear half. I built a tubing bender using a JD2 bender, and converted it to air over hydraulic. I used this to bend the rear frame, as well as replace one side of the crash bars that were banged up.
I'm still working a ton, so progress has not been as fast as I would like. I hope to at least have the rolling chassis at Portland this summer.
