No <i>XT</i> coupes .....
but a few 66-69 US Falcon coupes. Aside from the '66's, the trans-atlantic styling digressed significantly. The earlier examples share <i>similar</i> front and rear sheet metal and styling. Front guards, rear lights and beltline were the same. Their '68 model year significantly differed for our XW.
For '68 the US maintained the earlier front guards with indicators in the bumper and adopted a somewhat unattractive flat, square rear lamp appearence. Dash and instrument clusters, similar in the '66 & '67 cars are chalk and cheese to out Aust assemblies.
'66/'69 US falcons were only offered in 2 sedan body styles; 2 door and 4 door. the 2 door was a pillared style. No "pillarless" sedan (or Falcon) was offered.
Front sheet metal was interchanable so any Aust front will fit. But..... XW/XY panels on the '68/69 look <i>weird</i> (those ugly hind-quarters. If you want one, I reckon go for the XR/XT similar one. That makes your XT 2 door!
