47-55.1 How to get cab level?

[Zippi]

My 49 leans to the passengers side. The distance from the floor to the center wheel opening of the fenders are all pretty much at 26" but yet the cab is leaning. The PO used "L" brackets at the back of the cab and everything looks like it matches from side to side but yet the cab is leaning. I'm just going to leave mine the way it is in fear of getting the cab level then something else being thrown off. These old trucks were not put together very well and we have to do whatever to get everything to come together as best as it will. Tics me off when I look at my truck and see it leaning but a lot of people don't pay any attention to it.
