When I posted what I posted, I was going from memory. But with your post, I thought I'd check.
I didn't post what was in a factory service manual, but what I remembered reading somewhere around 1972 or so. However, I have a Factory 1970 Dodge Challenger/Dart service manual on my desk right now, and on page 7-10, towards the bottom of the page, it says 318/340 standard pump blades 4.38" - 8, Air Conditioning 3.70" - 6.
I guess my CRS isn't as bad as I thought.
