[BR3W CITY]

Thanks guys, I found out the little star-shaped piece is the spring retainer, which I'll try to get out in one piece...I think I ordered the deluxe repair kit, which should include another, but you never know.

The unit itself was out of a 97-ish astro van. The angled bracket might get replaced, as I think it might put the booster at a strange angle. The rebuild kits for the Chevy/GMC/...and Dodge are all the same...apparently the hydro units on cummins trucks was the same basic design, with different master cylinders/resevoirs.
