yeah i guess 3" would work, but that'd be pointless. since your body dropping 2 3/4 inches that would only leave you an extra 1/4" of space under the bed to hide the notch and stuff. you'd still need to cut the bed out for the notch and differential. i assume your laying this truck out... yeah?
i was thinking more like 6" or possibly more. have the wheel tubs touch the top of the bed rail. weld it back in there. that way your tubs will stay intact, and your diff and notch will stay under the floor. it'll be shallow, but it won't be cutout.
you'll need longer bolts, because when you will have to use spacers to put the bed back up to the right height. ok,say you body dropped the cab 2 3/4 inches and the bed 6"... you'll need to make 8 spacers @ 3 1/4" long and your bolts will have to be that much longer than stock. what you might do is look around and find an assortment of long bolts available and kinda go off that... it'd suck to bodydrop your bed TOO much and not have bolts to bolt it back on.
