Not sure who says an A6 can't be used cycling. I had a '77 and a '79 Pontiac Bonneville with A6 compressors and pretty sure both had cycling systems. The '77 had almost 300,000 miles on the original compressor. Ford also used them. We had a '79 LTD that had an A6. I don't know if it was cycling or not.

I have installed a few of these kits with no big issues. Put on a '71 C10 and a '67 Firebird. Both still going fine as far as I know.
