I have a 1970 440 Challenger I purchased in pieces and I am trying to figure out what brackets I need and how they are set up on the engine. The power steering is ok and I have the correct compressor. What I am trying to find out is how the alternator and the idler bolt up to the head and the waterpump housing. I have attached a picture of the brackets that I have but do not know if any of them are correct or what I need. Can anyone help? Thanks, Gerry.

Here's a previous thread about the big block A/C brackets and idler... link And this site has some good info and also sells any parts you may be missing.. http://www.bouchillonperformance.com/BPEalternatorbracketkits.asp

Not the best picture, but hopefully it will help.

If you don't already know it the bottom adjuster arm in your picture is extra..

I just went out and tried the setup. It looks like I have everything I need! Thanks for your help! Gerry.

You didn't show it in your photo, but there is a plastic coated metal bracket that mounts towards the top and holds the neater hoses away from the fan. It looks like a single blade of a fan.
You can somewhat see it in one of the photos.

Also, does anyone know if anyone reproduces the tensioner pulley? Or maybe just restores the bearing?

Thanks

Are you asking about the A/C idler pulley ??? Here's one about half way down the page... ... idler

Yea.
I was hoping for one that was more original (didn't have the bolt running through the middle). These work, and will be my fall back.
