Here is a picture of what I came up with for my 408. I am forced to use an underdrive pulley to fit the engine into my 56 Dodge so the standard Bouchillon brackets wont work. I have to fabricate my own. I don't see how the compressor will fit on the passenger side because the length from the back of the compressor to the pulley will be too long. (I have the "shorty" Sanden compressor here) Also the water pump outlet will get in the way. You could posssibly switch to an older style front cover and pump that will put the water outlet on the drivers side but that will involve swapping out the PS pump and brackets, and they are not easy to find.

This pic shows the engine set up for a GM alternator, there could be enought room with the stock MOPAR Alt up high where it belongs.

Good Luck.
