E55 w211 Acc Idler pulley - Where to buy?

I know I can go with ASP, but just the broken one; can be purchased separated? I remember to see that one for just $20. But dont remember where.
Also, in case I didnt found the OEM one, the ASP can be used with the OEM SC idler?
Thanks.

Looks like this:

I'm using OEM screw and ASP separator. The ASP (accessories) one touch the housing, that's normal? There are anything needed at the end of the screw?

I also change the bearing in the SC one! The position looks correct. Maybe because is in aluminum I feel the touch a little bit more.
I will call ASP to verify.
Thx
Anyone can help plz?
