Thanks for the picture. By the way, how long did this project take? I have the service manuals--looked them over and the job looks doable but time consuming. About the stop leak--certainly an option to consider, but not without risk. Some AC techs will not work on a system serviced with stop leak because it can be very damaging to reclaim equipment. Also, in some cases the stop leak stuff can gum up compressors, expansion valves, filters..... Would only consider stop leak for an evaporator, and then only if you are willing to risk having to later not only replace the evaporator but other components as well. If there are other considerations, I'm all ears. (or eyes in this case as I'll be reading them on a computer screen)

Thanks for some very helpful replies.
