I want to add an extra idler between the alternator and the power steering pump to reduce the belt slap there. Does anyone have any details / specifics regarding the pulley, spacer, or the flange bolt required?
The idler spacer / bushing is proving very difficult to find around my city.
If anyone has a known part # or source for these items that would be very helpful.
I believe Zack and Blazen71 had posted about this in the past but I can't find these posts.
Thanks!

lji372 sells the stand-off. PM him. Then get a smooth idler pulley. Can’t remember the size but I think there’s only 2 diameters. Get the smaller. Use a longer bolt or use a stud like I did. If there’s a big lip on your water pump pulley you may need to machine or grind it down if your new idler hits it.

I'm looking to eliminate the double pump process I have to follow right now to get the pedal hard

Will do thanks for the replies. I have had zero luck trying to get an m8-1.25 male to female stand-off bolt here locally. For now I am going with a slightly shorter belt the 1073 vs the 1080. (I'm currently running the 3.70 super charger pulley).
There are 2 pulley diameters a 70 mm and a 76 mm, the 70 mm is definitely the one that's needed for this as blazen71 mentioned the clearance issue around the water pump pulley.
I will pm lji372 for the stand-off bolt. (hopefully I can figure out how to send a msg, lol!)

I’m using a gates RPM 108 belt with a 3.4 pulley and stock tensioner. Puts the tensioner at 50% travel, perfect for rpm belt. No slip at all!
