In summary, these five types will be flying around this summer:

76G = ex-Gulf Unrefurbished; 5 rows of BE recliners; 29BE seats for sale
76U = "regular" Unrefurbished: 6 rows of BE recliners; 35BE seats for sale
76L = Refurbished 9 rows of flat-bed BE seats; 35 seats for sale; 175Y seats
76T = Refurbished 9 rows of flat-bed BE seats; 36 seats for sale; 172Y seats
76Z = Refurbished 6-7 rows of flat-bed BE seats; 25 seats for sale; 200Y seats

By January/February 2014, the 76Gs and 76Us should be gone, and we should be left with the 76L, 76T, and 76Z.

Note that this is the 767 mod thread, and there is a separate one for the A330.
