....well my 2011 Ram 2500HD tow mirrors turned up and guess what...
...they only work perfectly
, mounting is exactly the same, wiring is exactly the same and all the features power/heat/turn signals/puddle lamps work exactly as they should. 20 minute job to swap em out... well chuffed!!!
Sorry snowrv didnt read your post until now, i'll whip em off again when i get a minute and note the part numbers for you as well.
I've even done a little "how to" here: http://www.ramforumz.com/showthread.php?t=107523
