No I did not notice anything wrong with damper upon inspection. It did have maybe 1/16" wobble at crank pulley compared to dead on straight with Summit or rebuilt damper. Here are close up pics. If you look at closely at about 1 o'clock you can see the rubber ring just slight deformed. On back side if you looked really close you could see just the slightest bulge at 7 o'clock (opposite side). Anyway bottom line- didn't really look like it was messed up to me.



Damper Doctor actually added a bit of confusion to the mix even tho they fixed the problem. My block is 1989-1992 360 truck motor (junkyard receipt) but Damper Doctor receipt said my damper was 1993. When I called to verify boss wasn't in, when I called back assistant said Doctor said receipt incorrect, damper was 1992. Never said if they found anything wrong, just rebuilt per request. Cost was $112 including shipping. Mailed Priority Thursday, got back Wednesday
