Supercharger Tensioner/ Double Pulley recommendation




I assume the "supercharger tensioner pulley" is this:

Is the double pulley this one?:

I read the DIY about swapping our the bearing, but I can't quite seem to figure which bearing to order for it. I have seen a few different option in there and other places, but nothing concrete.

11 = tightener pulley, part #1132020419
29 = belt tightener, 1132000170
8 = tightener pulley, 1132020019
23 = belt tightener, 1122000970
V-belt, 1139970292

I just want to make sure I am ordering the right components based on their wording.
thanks
