I used Vintage Aire in my '62. Unit went in well and does a great job. Only complaint I have is minor. Compressor mount is high on the engine and prevents the use of the factory air cleaner. I have a SBC in my '62.
I will be fabricating a mount that is a lot closer to the era factory mounts for the SBC. That will move the compressor out of the way. Not sure how that translates to the Stovebolt 6's.
