If it wasn't ... it sure is now! The problem with finding V8 parts is that with the two piece z-bar it was easy to leave the mounts in the car when swapping over to automatic which is probably where many of these parts come from. I used to have a 73 302 car that was a 3 on the tree. I swapped it over to a C4 when I put a new engine in it ... .. I know for a fact I left the frame mount it in .... and trashed the z-bar and rest of the parts.
