zero rate add a leaves can give you 1.5" of adjustment either way, move your rear shackle hangers back 4" and install a set of 56" springs (but install them backwards), 52" spring swap in the front is supposed to move the front axle forward like 4". so in theory, you could get almost a foot of extra wheelbase pretty cheaply.

i plan on building a Blazer at some point that uses all of the methods i just mentioned (remove 52" springs from rear, install in front, backwards 56s out back with a shackle flip, zero rates on both ends. its been said that the SWB trucks are the best compromize of stability and maneuverability of any factory offered straight axle truck, adding approximately 11" to the Blazer's 106" wheelbase should get me pretty close to that happy medium, while being a fairly capable truck, without alot of $ invested. 52s are pretty soft springs, so if the truck is to see much street time, sway bars are definitely a good idea.
