1978 K10 Suburban Suspension Assessment

[RyanAK]

Hey, guys. I have a more detailed thread of what I'm trying to do up in the squarebody forum, but thought I'd ask some simple questions here too.

Here's the thread with all the details: http://67-72chevytrucks.com/vboard/s...d.php?t=808476



Basically I'm a little concerned about the front springs and my rears sag a bit with a full (40 gal) tank of gas. Looking to go back to stock or "stock plus" but could use some eyes on my current suspension. Rides nice enough as it is... but I think it's time to freshen it up.

Front: Gaps between leafs (I can get a finger between them...) and the front axle isn't centered beneath the body. Negative arch, but still pretty good distance to the bump stops. There are marks on the main leaf from the stops though... Bushings need replaced. Tired shocks. Something to worry about?







These are the best photos I could get showing the off-center axle:








Rear: pretty flat with anything more than 1/2 tank of gas that gives a noticeable sag. 'Chevy Lean'. Broken leaf pack clamp. Bushings shot. Tired shocks. No broken leafs though.







Thoughts on what I've got and what should be done? Appreciate the help.
