I use one of those carrycase jobbies with the transparent lid. Its got 4 large tubs in it that can be sub-divided into 3 sections each and then 2 tubs that are half the size of those ones. Had it for ages but you can still get them (or similar) from DIY stores. Plenty big enough for wishbones, shocks or even built sub-assemblies like XXX-CR rear ends!
. By the way, that's a nice collection of rear pivot blocks you have there, I've never seen one in one piece before, all mine seem to have been in 3 pieces when they come off the car
