I have a 2X6 Small Bros evaporator that has had the rear legs broken off.  Looks like someone tried to drag the unit across a floor (I never got the broken pieces with the evaporator when I acquired it).  I'm hoping I can purchase from someone out there either the complete leg assemblies or at least the castings which bolt to the evaporator at each corner on the back (I could buy the piping to make the legs then)  I suspecy the castings would be the same for a host of different sized evaporators.  I do have the broken castings at this time and can flip a pic to compare (I just didn't know how to post a pic with this ad!)  You can contact me at rkjk@sympatico.ca or phone 613 432-7308 Renfrew, Ontario, Canada.  Thanks, Ralph
