I have a nice advertising cabinet from the 30's-40's for sale on eBay right now, it is packed with NOS parts for the Kem fuel and vacuum pumps. I'm not sure if MOPAR used these pumps but you car guys will know.

There is an envelope inside that mentions models up to 1941 so I'm assuming that these parts are all from that era, there are parts numbers on the cabinet drawers.

This auction ends Wednesday night (9/19/2012) please check it out if you can use these parts and I thank you for taking the time to read this.
