Greg,
All coventional ADs had a front mounting under the radiator cradle....if the rubber's gone, she'll bang like hell !
I had to do this as a "budget repair" on my '54 when I was in high school and used a layer or two of tire carcass.
I think the bolts that go through the radiator support and into the frame are carriage bolts, and mine kept spinning as I tried to remove the nuts...I think I jammed a fat cold chisel against the head to keep 'em still enough to remove the nuts.
Good Luck!
