Springs are assembled. The clamps I bought were underwhelming. It took enough effort to remove the one I replaced to convince me to leave the others in place. Two of the factory clamps were missing so I got some square U bolts to replace them and fashioned some new straps. Do they look nice? No. Will they work for my situation? Yes. I probably don't even need them. Also on the list of things I probably don't need are new bushings. Two are shot, two are good. Depending on how hard they are to press out, I may not replace the ok ones. I just don't want any undue slack while I'm fitting the 14 bolt. There's also a fair chance those springs will spend more time under the truck than I intend, so I want to give myself the best chance at success that I can.
I'm limiting myself on how much I spend each paycheck because despite what I tell myself, this will take a while to to get drivable. So I'll buy the rest of the hardware to mount the axle when I get paid again. Probably.
