My sled is a 12 and has all the engine and electrical components from a 14 swapped into it, regulator is located on the clutch cover just like the 14 believe its all 14 stuff came from a tunnel damage sled that had less than 400 low miles and swapped to this sled that had a bad original engine.
feel a lot more confident in that swap which is big reason why I bought it have always heard the 13 up motor didn't have the issues like an 11 or 12, this swap was already done when I purchased it. next summer no matter what miles I'm gonna install a fix it kit in the top end, Might want to check in to this for the newer engine your swapping also.
Put the 13 running boards on your 11 and you`ll love it even more.
Good Luck. Wildcard
