Check out his build thread. They sent him motor mounts that look like solid motor mounts but I think there is some rubber in there, but it's nothing like a typical motor mount. And there's a metal plate behind the motor mount. He's going to toss the metal plate and just bolt the motor mounts to the sliders.
Surely somebody has ran this CPP set up. Brian?
I only did CPP stands and then used typical GM car motor mounts 1959-1970's, and then some Ebay 3 position adapter plates that I had to mill down to just under 5/16" thick.
