XT M739 rear mech, must be in very good or NOS condition

I'm not 100% what the difference is between the M737 and M739 mechs but I do have a couple of M737's in this thread viewtopic.php?f=2&t=277459
 
The pivot pins in the M739 were slightly larger making them less prone to developing "slop".....other than that no difference I think. Either are pretty bomb proof mind.
