body drop bed help

i did a 2.5" body drop on the cab, but i am now going to be working on the bed and rear suspension, what do i need to do, to prevent from cutting a big section out of my bed floor, for air ride, i am going to mount my bags on my lower 4-link bars, do i have to do like a 4" body drop, and space up the bed to clear everything, or just do like a 3" so i will have some play to make all the body lines match, i dont mind notching out for the frame notch. i just dont know how high that rear axle will come up, what size of notch will work for my application. i am going to be running 205/40/17" tires if that helps any
Thanks

it all depends to get my bed to lay out without a cut into my bed and setting it up for the lowest pro 18s i just needed to do a 3 1/4 but im assuming you need to do a 5 or 6 to clear the bed and everything with bags

roknmotor,

i'm deff not a body expert, but i'd say that since the cab is done, you
could just cut the floor out of the bed, put it on jack stands to match
body lines on the cab, and reweld the floor back onto the bed, then do
any cutting of the fender wells and bed floor that needs to be done to
clearance the notch & tires.

just my 2 cents....
