in the front main springs on the K series (80 model) trucks between a 1 ton and a 3/4? The truck I just bought is a 1 ton single rear wheel truck and it has a busted front main spring at the bushing eye. Is there just a greater number of leaves on the 1 ton? Don't want to spend any $ on the truck as it is a rusty tub and only for donor. I can probly locate one out of a 3/4 ton if they are indeed the same. I would like to drive it some and see whats what and whats not, before I start its demise. Thanks for any info!!
