Default LS5 Idler pully Set Up

Hi, can one of you gents help me out with installing the idler "pulley"? What I need to know is what two points do I mount it to.

This is the type I have. I need a good picture ideally to see the mounting points on the head/block/water pump for the two mounts.

Love answering my own questions

Looks like the top adjusting bold is actually on the lower water pump mount. Found my own dissasembly pictures of this area (forgot I had some of this assembly...gotta love the digital age!).

Do you have any pics of the idler with the power steering pump bracket installed? It looks like the lower mounting kit uses the upper p/s bracket hole?

I just checked my '71 idler mount, and yes, the lower bolt and spacer uses the upper p/s bracket hole.

FYI - My picture is for a non-PS application.

Maybe that's why I think I see an extra spacer in your diagram.
May I ask, what size belt are you using for the crank to water pump pulley?
