I just did this on a LS7 570 crate. I installed a Holley mid mount with the ATI damper. The Holley, nor ATI instructions have any info for the spacer used on the dry sump crank and extended timing cover on the LS7. After talking with ATI, providing dimensions, etc, they basically told me with the GM crank spacer, the damper is moved out to the seal the same as an LS3, so a LS3 damper, as well as accessory drive kit, is what is required. Holley has updated the mid mount info on the website to reflect this.
My crank hub looks pretty much like yours. The crank was recessed a couple hundred in the ATI hub. ATI confirmed this is correct.
