This sounds a bit off to me, but maybe I'm in the minority there. I bought a Delco booster for my Jimmy, it already had the purple seal on it, and there were no sponges to speak of. In my experience, there was no transfer of parts required. Maybe someone else knows what you mean with the sponges, but I'd like to see a picture.

I don't think it went through. It just says "IMG."

It's alright. And I see what you're saying now. The purple thingy goes over the rod, which you already knew, and if I remember correctly mine had the black felt bushing, and I left it on there. I don't remember the white sponge at all so I don't want to speculate that it's just packing material, and it's not. This is how mine looked going in facing the cab side.

You're welcome. I wish I could say 100%, but it's been a while, and I didn't think too hard on it to be perfectly honest with you.
