Suburban HD leaf swap advice

[fatkid216]

Hey guys, just picked up a 78 Suburban k10 with a 4in lift, new leaf springs up front and blocks in the rear. I like the height of the 4in lift but the rear is sagging. No money for a new lift right now, but it looks terrible, so I figure a good cure for this is getting a set of 3/4t springs from the local pull it yourself junkyard, it will only cost me $50 and will keep it from happening again. my question is should I get 3/4t or 1t springs? will 1t lift it more? and will it make the ride more harsh or is the weight of the suburban enough to make it feel ok? if I found springs from a newer truck would it ride better? Thanks in advance!
