Thanks very much for the info.. I suspected I was doing something wrong..I was not aware of the thimble nuts.. I will go out an purchase a Budd Socket set. I was planning on using the 20" wheels on the rear and 19.5 on the front. trying to keep the truck as original as possible. Found a local shop willing to mount tires on the 20" wheels if I decide to go that route. I have been looking for 22.5" but no luck. Hopefully I locate 4 wheels before I get to that stage of my project.. If not I will be forced in to using the 20"
Thanks Again
