Hello Robb,
I was in the same spot as you just a few weeks ago. I had ordered the front engine isolation mount and found out that I had only been sent the rubber block. I took the old mount off a truck with a 216 and lined it up with the front engine mount plate and found that the holes lined up. You might have to purchace a new top heat deflector plate because mine was worn thin and corroded through. The bottom plate was in good shape and I decided to keep that. There are two bushings and two large penny washers as well as four carriage bolts that hold the entire assembly down. If you want a drawing, I can fax you something with measurments and a parts breakdown.
BIG LIFTER
