go to http://www.partsamerica.com/
and type in 2254 in their search, then click on "Anchor 2254" and it should give you a pic. I think this is the right one, but not positive. They list none, or the wrong one, for your car. It looks like the 6cy mount, only not as wide.

The metal frame brackets come up, and a bolt goes thru the center hole from the bottom to keep the mount fastened to the frame bracket. The rubber is sandwiched in the mount, which bolts to the engine thru the two ears.

That's the # that anchor lists on their site... 2254. They list the wrong one for the 6cy though

ps the frame brackets will be different than the 6, or the SBC brackets.
