318 to 360 motor mounts (confused)

Pre 73 Mopars with a 360 used to be a common find in the junkyard. You could just go to the core pile and grab the mount you needed for five bucks. Not so much anymore. I was going to send you an E-Bay link to some but there's a Buy it Now for ninety bucks. Seems a guy could male a pretty good living modifying 318 mounts.
You can use the unmodified 318 mount to get the install done and even run it that way. Depending on the setup you could probably run that way forever.
