I bought a high output alternator for my 70 Challenger which has a 340 cu in engine and a stock a/c compressor.   When using stock mounting brackets, the alternator width is such that it hits the passenger side valve cover.  The valve covers are aluminum the aluminum "Mopar Performance" type.   I still have the stock valve covers, but they don't appear to be the same dimensions as to MP version.

The Google searches I've done so far failed to find a commercially available "low mount" bracket option.   There were several older posts on Moparts where folks fabricated their own brackets.   

If anyone has a source for a bracket that will work, or a drawing or picture of what they've used to deal with this situation, I'd appreciate seeing it.

Thanks.

I'm going to answer my own question.  No dice on a low mount alternator bracket from any before I could find including Hughes Engine and Mancini.   There was 10 year old post on forabodiesonly that indicated a barracked might be available from Bob Mazzolini Racung, but I didn't follow up as a simpler solution was found.

My new alternator is a 150 amp output unit from Quality Power in California. After talking to Kevin at their office and sending him a couple of pictures, he recognized that the issue could be resolved by simply mounting the alternator on the front side of the lower stock bracket as shown in the picture below. I may have a little shimming to do to get all the pulleys to line up but this gets me really close to right.   I still have to get a spacer for the top but I'd be doing that anyways.  I'd been staring at this thing for hours but couldn't "see" this simple solution.  :headbang:

I have to say that Kevin from Quality Power was very responsive and helpful. I'd buy from them again in a heartbeat.

Very cool , often there is a simple answer but you really have to be there in person to see it in 3D
Glad you found a way to make it work !

Sometimes the KISS principle is the best principle, eh? Congrats on sussing it out and sharing. Please post more pics when done and give us the skinny on what finally had to be done.  :bigthumb:
