Thanks for the photos...that looks like a project to keep you busy for a few years!
I considered the aftermarket hotrod mounts, but this car will be driven a lot so I elected to go with the latest stock Mopar mounting system. Having a generic motor mount fail in the middle of nowhere is something I would like to avoid.
The spool type mounts are available anywhere and usually for less than $10 each. Even NOS can be had for $35. I didn't think it would be difficult to find the saddles they fit into. I have a couple of prices locally, but I can buy a whole car for not much more than what they want for five minutes with a Sawzall!
