Actually I was looking at my 73 parts catalog and I think it will work for me trying to decipher how all the brackets go. It showed like 6 brackets total. I know I don't have six. I've got about 4. So hopefully that was right what you said and one was for 440 only. They pretty much all are retained to the intake in some form except the big front mounting bracket that's attached to the water pump housing. I would post a picture here of the illustration but the whole cd is one big pdf file and I don't know if I can pull out one page. But it's from the 73 Chrysler parts catalog under air conditioning.
