292 4.8L Motor mounts issue--need some help

[hemifalcon]

luvbowties--thanks for that link. It clarified what everyone else has said about the passenger side tower/perch being "smaller" in contrast to the driver side. But--the ebay ad actually helped. I had a bag of "extra stuff" which was full of grease from when I disassembled the engine initially--and lo and behold--I found the spacers shown in the pics.. Saved....

Mount brackets..





Here are the towers..




Hopefully this will help others as well.
Thanks again guys.
