Correct part number for the tensioner assembly is 49281,which is a Goodyear replacement unit with a much better pulley than stock GM.It is still plastic,but a better grade and design. The correct steel idler pulley is 49036,also a Goodyear number.This has a much better (stronger) bearing and fits in place of the stock one perfectly,IF you reverse the pulley and the inner mounting bushing to the outside and have the bearing ride directly on the face of the bracket,which will be fine. Consider this upgrade, as our setup is constantly pulling on this pulley as it is on the drive side of the belt between the crank pulley and the blower.(lots of pressure) After 1k miles of track time,my idler was ready to die. Better safe than broke..
I'm putting one of these in the spares box as well

How come that bolt & washer looks off center?
Isn't there suppose to be a bushing in there to center it?
