My old A4. Original unrestored (except paint). Good for a comparison.

If it's an American "Nebraska" built bike - could it be in the same range as the LTD?

Year & Model
'76 KZ900-A4
Color(s)
(1) Dia Dark Green

USA MFR Z1F-500001 - 510340

So, it fits an A4 Nebraska spec - not much between the A4/5 & LTD apart from obvious bodywork, wheels, rear disc, pipes, shox...
The LTD:

Classic Red

Engine No. Range
Z1E086001 - 117973
.....which rules out the frame!
