They don't work because that post was originally made over 3 years ago and whoever owned chryslerparts.net decided to move the pages, sell the domain, or just direct you to that other site. We don't have control over that, nor do I know if those E-Fiche catalogs are still online somewhere - they really were a good resource. If anyone knows where they are, I can update the links.
