No the 8M80LAL5@#$%B =

8=Holden product number, M=Model 80=Body Style, L=6 Cylinder, A=Year of build, L5= Pruduction Plant, @#% = build number, B= last letter of series code.

K=80, A=81, and so on. This is straight from the WB service manual supplement. So its age is identifiable from the vin plate number and the statos are the same.

the AWB, BWB bit is the the chassis number, which is on the year / month tag which he is missing.

but the number should be on the chassis near the steering box..

i was told that my WB stato (AWB500500) was april 1981 or thereabouts. so yours will be close to that.
AWB would be 1980 built as its the first ADR letter?
