i know alot of people that dont have anything going to they're package tray support and havent had anything weird happen.. i was a little sceptical at first when i cut mine.
also digby's dart is cutting 1.12 60' with the stock 20 inch segments. on a 275. . with basically with the same stuff you have.. srd bars, arb, springs on the rails with sliders..
i would call mencer for your shocks he revalves afco DA's for leaf spring setups..
