Here is what I did on the '37. My truck came from the Flint Hills of Kansas. It was used a plumbing and heating truck. The springs and all the attaching points were worn, much like yours. I replaced the shackles and bushings with new from one of the venders on this site. The front bushings were also replaced. I was replacing the rear axle, so new u-bolts were purchased from a local spring shop, nothing real special. The leaf springs were grooved from the rough use, so I tore them apart. I used a grinder to remove the sharp edge of the grooves, and rounded over the mating edge of the leaf under it. I did this on each leaf so they would have room to move when bouncing. I was careful not to cut any deeper. The clips are made from simple 1/8"x 3/4" strap steel and a soft rivet. I found the rivet at my local hardware store. They are concrete anchors I cut down to length and peened over with a heavy hammer. Before assembly, I added teflon strips between each leaf. Grease or paint will not last, the liners has been in for ten years now with no problem. The liners made a drastic difference in ride and noise once installed.
Its nothing thats to hard to do, just time consuming. If you decide to use new springs, I would still pull them apart and add the teflon strips. I replaced my front springs and tried them as delivered. The ride was so harsh, I removed them that afternoon and bought more liner material to add to them. Since then, I have removed 3 leafs from each corner of the truck for an even softer ride.
