I have Custom Works rear shackle kit, rubber on front spring eye and lower shackle. Delrin on upper shackle. Rubber needs to be where it is to allow spring to articulate.

+1 on that. If you are just doing the shackle's and not the front spring eye, you'll be good.

I think I would go with Custom works rear shackle kit of Delrin for upper, rubber for leaf eye, grade 8 bolts and heavy duty shackles with 2 sets of spring mount holes. Does not appear Keith @ Custom Works has upgrades for the front leaf mount but there are options through Dave at Pro Touring F Body; Spherical bushing for the spring eye and an improved front spring mount.
This is what I used.
