I haven't installed the AC Delco variant -- but I did order one when trying to find the correct length I needed. While the cardboard said AC Delco, the belt itself said Gates with the green backing and all.@NorCal_03Cobra Do you have any experience with the AC Delco version of those belts. Reason I ask is, I have been getting green belts that say Made in Mexico on them and the quality is not that great.
