Most of the 76Zs will eventually get modded to the 76K config.
Currently, that is true.....There were "T"s (7 frames) that were DL's longest range 76E's and were sold to Amazon which were converted to Freighters. Delta still has 1 "Z2" version still in service (N394DL), but at one time had 5 total. 4 have been sold to CAM, and have possibly been turned into Freighters, but I have not verified that.
www.rzjets.net website I have used in the past to see what the 4 are currently being used for.
