i was doing the "junkyard crawl" at Pick and Pull for some Magnum heads (which I found...) and saw a 74 Valiant with power everything. I took the brake booster assembly as I know they are getting hard to find. What I didn't recognize until I got home is that the rod that goes in the cavity that pushes the piston on the back of the MC is gone! Did I buy a paperweight or is the rod still around somewhere...
