So the hz motor casting date is 19th May 1978 which would be in range for the 7/78hz and the second is 21st July 1976 which would be ok for the 8/76hx

Thanks Rodney I think the HX 21 July 76 should be too but has the WA police number I guess without some old rego info I wont be able to find out as Holden have told me they dont have the records any longer
