@jimgmc. Thank you for the info. I will look for the numbers
@52Carl I am not having any spring issues now. Was just trying to update item as I go. The shackles need replaced for sure so I thought I would replace the spring before I had an issue with one of them as well.
Thank you everyone for the replies.
If this were my truck, I would remove the springs from the truck and remove the bushings from the springs and inspect the spring eyes to make sure that the bushings did not wear all the way through and damaged the spring eyes.
If there in no wear there and the springs are not heavily pitted from rust, I would use what you have.
New springs are generally stiff. They are designed to do the work which these trucks were designed to do. Haul heavy loads. You may not like the ride which new springs may provide. I doubt you are planning on hauling much in your truck, judging from its stance in your pics.
