Ya and I looked up CS-644 as soon as I saw the number listed here. Summit said "not available" as did Rock Auto. I couldn't even find it listed on Jegs site.
Whoever thought this stuff would be so tough to find? Melling, Sealed Power and the like used to be available in EVERY NAPA store in the country and sometimes IN STOCK. I never thought I'd see the day. I guess we're just dinosaurs.
