how do i lower my truck?

[randyjohn]

i've been doing a lot of research on this and other websites over the last few months and still and scratching my head as to how i will drop my truck in the back. i'm looking for a 3/4, maybe a 4/6.

it's a 74 gmc 2500. it has the 14 bolt, 10 1/2" ring, 8 lug rearend (3 1/4" OD i think). 9 leaf springs. from pictures i've seen of stock 1/2 ton spring mounts they're the same. there is 7 5/8" clearance between the axle tube and bottom of frame without the bumpstop and 7 3/4" clearance between the top of the diff and bottom of bed so a c-notch would be moot i think.

the front i know they make spindles for because i have 1 1/4 rotors. the back is what's got me stumped. i would actually prefer bags so that i can still haul a heavy load with it (it's going to be my hot rod shops parts runner and maybe have trailer duty). as far as bags go, do i ditch the leafs? take a couple of leaves out and use helper bags?

any insight or ideas are welcome and appreciated.
