I believe that Dynomax sells an adapter to use the stock mount in some fashion. I think they include it with their headers, but I could be wrong. The bracket might only work for the newer rotary type compressor. If you find anything out post it as I'll be interested myself as I have a 69 with A/C and I'm putting headers on.

I used the stock bracket on my 72.
You have to grind header tube clearance in one area.
There are two bolts that will require a shim out. On mine I used heavy wall tubing cut to length. Then one side of the tubing must be ground so that the tube cross section has a "D" shape. This is because of the bolt to header dimension.
If I had a digital camera I'd post pics.
Put the headers on. Then position the bracket and you will see where and how to grind it.
Next measure the stock cast iron header bolt flanges and duplicate that measuring from the head itself to get the tube length.
All that done, and the a/c pump should allign as before.
