Finally get to pretend I am one of the cool kids - Holley kit swap

Seems like there is some slop. I can look at the /6 k-frame when I get home.

Motor mounts are not slotted.

Worst case I will probably just push the inner fender in a little.
Remember, the shock tower is behind it, so don't get "real" carried away. You don't need much at all for a good gap.
