Any time guesstimates?

I did think you had to do any grinding with the 3/4 ton axles (calipers) same as the 1/2 ton ones 15' should bolt right on.

Its not really the calipers that need grinding as much as their mounting bracket.

Yeah I had to grind mine for a while (calipers and backing plate) in order to fit my 15's w/ 4.25" BS...
