Just picked up this 73 Chinook 2500. I am not finding much information on them anywhere Any tips would be appreciated. It's in pretty complete shape other than the missing genset and medicine cabinet. Want to keep it fairly original. Looking for information on sourcing windshield and front and back window rubbers. Picture of medicine cabinet would be helpful to try to match it (close anyway). It is supposed to run but that is yet to be seen. And electrical.... Charging system info. There is an old 70s portable battery charger in there to charge with. Does not look factory so information there would be helpful too. Thanks.
