I noticed when putting on the oil pan that the Damper was not up against the oil slinger/timing gear... so I ended up making a crank spacer so the Damper would push up against the oil slinger/crank gear and not hit the timing cover. Good thing I caught this. I dont know as of yet if the crank gear that is a CAT Gear Drive set up is thinner than the original crank gear is or if the Damper is a little shorter on the snout. I will take some measurements and post my findings.
Here is the spacer.....
