New 6 to V8 mounts being made.
For what it's worth, I have spoken with Barry many times over the last year. He and his partner have been great with customer service and the brackets I received worked perfectly for my 5.9 install in my 65 Valiant using original-style 273 isolators. I purchased them over a year ago. They were cheaper then.... check out post #46 in the link in my sig for pictures.
