63 c10 rear step notch/new rear clip help

[jserrato714]

Hello peeps....I want to pretty much lay out the bed.....I have done it before with a huge step notch but that truck had leaf springs, My 63 has trailing arms which you all now hit the frame at one point or another. How low can I go by leaving the arms and using axle mounted brackets for the bags?Any pics of those?I am trying to avoid making a new rear frame piece but is that the only way to lay out?The step notch is around $180 and the metal which I need is half of the price.....any ideas as to whats the best way ?I have done lots of research and browsed through many pics but no close ups or measurements as to the lenght of the cuts,angles, etc. thanks
