CS-144 alternator bracket
When I upgraded to the CS-144 alt I was faced with the back bracket issue. I did not want to connect anything to the exhaust manifoild becouse of the heat transfer issue. But I felt I needed some support on the back side. Here is what I did.

What about the support in the front-back direction? That supporting bracket you installed is doing the same thing the bracket connecting to air pump was already doing. Which is (mostly) providing the sideways-directional support.
That original bracket provides the front-back directional support. I personally had to alter it's connection at the headers a little bit when we installed LT headers and as a result, the supporting direction is better than original (more front-back directional):
Notice the little bushing at the alternator side, which raises the support further away from the electrical connection.

I think the bracket is also there to provide up-down support to the rear of the alternator. in any event, it being diagonal, it provides both. heat transfer through the bracket is a non-issue, it is dissipated.

Putt your hand on the back bracket after a nice long drive... No really if you have a non-contact pyrometer take a reading. it gets header hot! And becouse it is made of steel the heat transfers right into the alt. After I installed my alt with the new bracket, I left the bolts lose and applied a force in different directions, It was well captured, so I was happy. I think heat is what shortens the life of alt.

If anyone comes across this ancient thread while researching their own bracket challenge, consider the following:
The rear bracket is not, as Yorcci believes, there to provide front-back support as much as it is to provide resistance to torquing about the alternator's vertical axis through the two mount points due to the belt pulling laterally on the pulley way out in front. Therefore, his revised layout is less effective than the factory placement of the bracket, which has it better situated to be pulled on. It's primarily a tension element.
