There were several grills over the years, in Australia we had different welded wire grills to the square woven mesh of the UK build and army variants. Many people believe the welded wire were fitted only to the 6 cyl, however I know they were also fitted to 88" which discounts 6 cyl belief.
Irrespective of the truth, what is fitted today 42 years after being built may have no bearing on what it had when it rolled off the end of the assembly line.
