Easiest would be to buy drop leafs to get the additional drop you want. I can't imagine running 5" rear without a notch, but I've never run suburbans maybe the frame is different.
You cannot get 3" drops spindles, 2" is all.
EDIT: crap just realized this is a 73-87 style truck that kept going till 91 in burb's. Yes, you can run 5" rear without a notch [my 78 does] and yes 3" spindles are the way to go.
