I agree with the Captain....as far as the I-6's go..
But somewhere in my memory banks.....back in the late '70's , I did a V-8 swap in a C-6o, and that one had the two bell housing mounts and one in the front center under the harmonic balancer....

Or maybe I was smokin the "Tall Grass" and just thought that's what I saw...
