Looking for a vacuum tree.

Hello,
I recently replaced the rotten 318 in my 73 duster with a good running 318. Unfortunately I bent the hell out of the vacuum tree on the new to me engine when I put it in and didn't realize until i'd given the original engine away on craigslist.

I had no idea how inconvenient it is to track one of these things down. I would like to find a 3 pronged vacuum tree if anyone has one for a reasonable price. I live in Monterey California (93940). It needs to have a brake booster nipple and a secondary at minimum. Thanks!

PS. I'm embarrassed but I don't know what they are really called.
