Ok so Im wrapping up my build this weekend. Installing RCDs dual fueler kit on my 6.4. Ran into a problem that my belt is waaaayy too long they supplied. Anyone have this kit and can give me their belt number? The one they gave me was a K081055HD. I measured this belt to be roughly 4 inches too long. Which puts me at needing a K081015HD or a K081005HD. Would make sense with either of those being only one part number off. Just my luck to receive the wrong one though! Anyone that can help?
