I had to add an idler to the mix to get it all to work. The power steering and alternator bracket is a purchased part and I decided to just modify it. It's already overly complicated and too many parts, but I added more pieces to it.
I added an angled piece to help support the pulley and used some b7 all thread and made a nut/ pulley locator.
That holds the pulley just fine.
Instead of keying the crank pulley I decided to convert it all over to pin drive. Each pulley has a set of pressed in 1/4" dowel pins and two slip fit holes on the other side. The mandrel has two pressed in pins and the nut on the end has two slip fit holes. It all stacks up together. This will not have any issues, it's solid.
All finished. Gotta find a belt that fits. If you are wondering how the belt is tensioned, the power steering pump has a jack screw underneath it to move it up to tension the belt.
