Well I was told by the guys down at the Pizza Shack in Little Italy that, the first thing you do is jack the truck up about 3 inches. Then you reset the Binotz fittings with a medium-sized flavitz bar (GM part #4ImADummie). Be careful reading the dial, though, as some mechanics have accidentally stripped Binotz fittings through over-torquing. That should realign your Johnson Rods very nicely and to factory specs. Check your Service Bulletins, though, as there might have been a slight change to this procedure in the mid '50's. While you're at it, this would be a good time to check the grease level in the Fallicalator. It really is a pain to be stuck on the side of the road with a seized Fallicalator (not to mention, misaligned Johnson Rods).
So ya think they are right or do some of y'all have a better procedure for this adjustment??
