When you click the "ACMOCArchives" button on the ACMOC home page it takes you to a page named "Caterpillar Track Type Machines" and then under that it has the heading called "Track Type Tractors -Diesel". When I click on the "Track Type Tractors -Diesel" it seems to be a dead link. The link goes nowhere. Is this posted somewhere eles on the site ? I recall that the page this link used to go to had all the series prefixes 6U, 9U, 1H... and gave the years of mfg for that series.

Yes I,ve been wondering where it went to also.My screen says item couldn,t be found.

Me too-couldn't find it...

Thanks for the FYI, I'll take a look. However, some of that info is incomplete and was copied "as is" from the old site.
