TWO Questions about A/C Compressors and brackets
. . . .
The first question is: Who sells the "small" A/C compressor that's painted BLACK, in the first picture below ? The second question is: What front, A/C bracket is pictured in the other two pictures ? The bracket I have on my original 70 350, is a lot bigger and hides the entire front of the valve cover. I seem to remember reading that there are two different brackets for two different water pumps. That small bracket seems to just attach to the head though. ( I'm going to have to re-install my large, DEAD, original A/C compressor for a while until I can buy all of the stuff to change it over - it just won't have a belt on it ) I'd like to use the smaller bracket, if possible. I'M CONFUSED !!! . . . . |

Re: TWO Questions about A/C Compressors and brackets
I have no clue to your 1st question. I have never seen one that small.
The second one is a factory setup. The third picture is missing parts. Here is my old complete setup.

Re: TWO Questions about A/C Compressors and brackets
I think the compressor in the first picture is the standard "A6" compressor, I think its an "optical illusion" making it look smaller than the others.
If your AC mounting bracket covers the entire front of the valve cover, It sounds as if you have the early brackets usually only used up to 1967 on the trucks, Sorry I do not have any pictures to compare the two styles of brackets |

Here is a picture of "MY" 350 engine compartment ( with the compressor missing ) with the bracket that hides the front of the valve cover. . . . . |

Re: TWO Questions about A/C Compressors and brackets
This picture looks like it's missing the stock front bracket as well. It's not going to run long without it if it is. It does look like it has a lower bracket fitted to it though maybe.
If my memory serves me right the smaller brackets are for later model trucks. 70-72.

Re: TWO Questions about A/C Compressors and brackets
Early V8 heads don't have the mounting pad and threaded holes on the front of the heads. The big brackets were needed to attach to the water pump and intake bolts on the old heads.

Re: TWO Questions about A/C Compressors and brackets
I haven't ever seen a black one.
That doesn't mean they don't have them though!

Re: TWO Questions about A/C Compressors and brackets
I too have never seen a black one, either dull aluminum or polished,
One thing to keep in mind if you go to the Sanden compressor the factory mounting brackets will not work, your hoses will also not work, you will have to use aftermarket, I do believe the ones shown are "Vintage air" setups. |

. . . .
The front bracket on this one will work good. I have to get all new hoses anyway, when I change it over, mine are ALL 41 years old and haven't been used in probably 25 years. . . . . |
