Istalled yesterday my ATI damper, it is very nice product but there was minor fitment issue I want to share. After installation I couldn't turn engine by hand, found that outer edge of damper rests on the timing belt cover. I marked it with black marker on the first picture. Second picture is of the cover after 5 min of grinding, there is enough "meat" there to do it

Damper OD where it interferes with cover is 172.5mm, it is larger than stock. Another solution would be to chamfer ~ 2mm from the damper. I hope I did not stress internals much and did not damage damper when tightened it against the cover
