Wade,

I'm afraid my rig is not an example that will help you much. I have a narrowed '68 Nova subframe grafted on to the front of my Studebaker frame. You may be able to find some useful swap mounts at Transdapt

Click on Engine swap kits.

Also check with these guys, they have excellent suspension parts and list "Chevy Motor mounts available:

Hope that helps, keep us posted on your project. We love to see pictures!
