My Dodges (WC56 and WC53) are marked;
8* 306BG=0986
and
8*306BG=0987
on the bumper codes, along with 3 colour star on the early 42 WC56 and
2 colour star on the later 42 WC53.
I suspect you need a good reference book on the 20th, and just find an
example. It does look better if you can get the markings absolutely
right, though.

Just so this message isn't without the ususal 151/Gama/etc content
---- I have seen both M151s and Gama Goats sold legally in Europe by
dealers, I dont suppose anyone would bother re-importing them to the
US, but they do appear to have been sold legally, no Hummers though.
