Springs and sway bar I just took off of my 77.
I didn't measure before I took them off so here is what I know about the springs. They were on the truck when I bought it. The coils are not stock and look to be of the progressive type. They are black plastic coated. I put them next to my new 5.5" Wild Horses coils, and they were 4.5 inches shorter. Due to settling I would guess they are about 2 inches over stock. The rear springs look like the same construction as the new 5.5" WH leafs I have and when placed side by side, they were about 4 inches shorter. They are a 10 leaf pack with a military wrap, bolt on retainers and poly bushings. I would guess that the are the 2.5" leafs. I got new u-bolts and plates so I'll throw in the stock u-bolts and plates too. With the springs on the truck it cleared 33" tires and was raked a little to the front. The sway bar is stock with all the brackets. Pickup only.
Rear leafs w/ u-bolts and plates $150
Coils are free with the leafs
Sway bar $50
