new guy with a rear spring question

[chailey]

hey everybody. new to the board. i've got a 72 k5 my dad bought brand new. i bugged him since the day i turned 15 to let me have it. low and behold, the pink slip was the only thing i got for my college graduation present. i've been fixing it up over the last year and a half, but still have a ways to go.

i put 2 inch T.C. springs on the front and blocks in the rear. the rear springs are shot anyway, so with 2 inch blocks, it doesnt sit level at all. i'm thinking about going with new springs, but dont want a really harsh ride (for a 32 year old truck...). i've heard rear springs out of a late 80's k5 ride much better and are the same length. has anybody used 89 or later k5 springs and maybe a 3 inch block? how does that ride? thanks
