Has anyone used a front seal from Napa, says Chicago rawhide on it?? Just wondering if it is any good, local Cummins dealer counldn't get one for a couple of days and Napa had it in stock. . also lloks like I will be replacing the front gear housing thanks to a KDP that the previous owner did not tell me about... . He tried to fiberglass the crack by the looks of it and did one crapy job. . Oh well, just makes ya' wonder why people can't be honest. . Sorry about the babbling... Just like to know if the seal is as good as Cummins?? Thanks, marc
