I'm drawing a _______ I can't remember the term enough to do a search, but what do you call a plate that you use to convert a transmission of one series of engine to another series of engine.
e.g.
B16 Transmission/ H22 Engine....

I've done a couple of searches for it and since I'm starting off with Transmission i'm getting a wide range of hits

Thanks in advance
