Thanks for that, just checked on Mancini where I bought them from and they don't say anything, but they do show a plate as well as some pictures that don't really correspond with the actual mounts.Looks like I'll be getting another order together.
If you were a welder/fabricator, you could cut the mount loose from the k-frame and move it back and then cut the TTI mount apart and shift everything to match. The Holley mounts move the motor forward 1.75" so moving the mount back the same amount would be an idea. But a ton of work to do, not sure the motor mount can move that much.
Even then, the Holley setup recommends a $150 90 degree adapter. So it's not like it is a free fix.
