Level rear bed mount with rear of frame?

[Diablo]

I recently bought a 1999 dually 2wd with an 8ft Utility body. I pulled off the utility body and going to build a custom flat bed. The height difference between the front bed mount and rear of frame is 2 5/8. Can't say for sure I was on total level ground when I measured, but it was close.

Front bed mount height: 28 3/4
Rear frame height: 31 3/8

So if I lift the front (spring spacers), the height of rear frame should come down and help level the the 2 points.

So if I measure the height of fender well and jack the front up so it is X inches higher, is that the same effect as the spacers...so I can see what a 2-3 inch lift will do or will the lift settle and not be exactly X inches?

What size lift will I need to worry about replacing other parts because the lift was too much for stock components? I'm thinking 2.5 - 3 lift.

Does anyone know what the stock distance from front center wheel to fender well was with 215/ 85r16 tires? Just curious if the front is sagging.

The level is only a spacer that will sit on top of your spring raising it X inches.

As for the mounting points. you can't really go from the ground. There are curves in the frame. I'm guessing that you want a perfectly level flatbed.

I would like it to be pretty level. At least to the eye.

I think I will go ahead and build it out and then see how off the level is. The weight is going to change things, so I should work on the leveling afterwards. I can add the lift to the front and then modify mounting point heights to get it to my satisfaction.
