Stock Helper Springs 66 C10

[ol Curt]

My truck came with helper leaf springs, or so it says on the glove box door sticker. My grandpa probably took them off at some time, although I can't imagine why as he hauled anything from gravel to livestock in the truck!

I found a set awhile back. I'm hoping to have them cleaned up, painted and then mount them. There appears to be a round rubber bumper piece on the ends that just bolts on. I would like to replace those. Anybody know where one might find something like that? Also, would they be hard to put back together if I have them disassembled and blasted?
I know I'm wondering a lot of questions out loud here, but...do you think a spring shop would be able to provide all of this...cleaning, replace bumpers, and paint?

I'm going to see if we have a local spring shop tomorrow and see if they can provide input. I thought one of you guys who do the factory stock stuff might know.

Thanks!
