I have known of an information source for our old GVs with the Oshkosh chassis design that was sold to Freightliner/Daimler and just realized I haven't shared it with this Foreforum.
My contact is: Les Michaels at fcccservice@daimler.com (or Mark Fraedrich if Les is out)
Seems they are the only two people that know about and have the info we need, such as current part numbers of old parts.
Just received two emails from Mark re the two switches that control the brake lights and control the cruise disengage when the brake pedal is pushed. He even corrected my chassis number that was wrong on the Foretravel manual!!!!!
The email address is a bit different so I am including it here: dtna_fcccservice.pool-id@daimler.com
