Thanks Alanwoodieman... I allready knew about the vanpelt's page...
but that only shows the 71GA number and ( or i misread ) doesnt show anything about the Y
Ford 6 - 90hp (G) - 71GA- 326,418 to 71GA- 414,366
So i would still be happy to get a prove that says the they put the Y instead of A in use for 1 tonners
Expavr.. here some more pics ;-)
