Disc Brakes?
 

Ok on my k5 I'm in the process of converting it to 3/4 ton I am going to be running 15x10 steel wheels I have and I know I have to shave the calipers in the front but am not sure how much? Also I would like to swap the back to disc as Well and would the diy4x brackets work with the same amount of trimming as the front i have a 14bolt ff rear

It didn't take much grinding when I put 15x8 wheels on my K20. Just went slowly, grind off a little and test fit, then grind a bit more until it cleared.

Before you start, slip a wheel over the studs and see how much it looks like you'll need to remove. A small amount will be okay, but I wouldn't want to take off very much material.

Have you considered 16" wheels instead of 15"?

Yes I have but it was cheaper to by a set of rims than a set of tires and I don't need a higher load range tire I like how soft my 33s are they grip really well and don't seem to wear bad at all 16s are really expensive in my area rims were 280 delivered and tires would be 800 at the cheapest in my area
