Got it almost 2 yrs ago, along with registry record #899 (69 W300). Craigslist, Richmond, CA (SF East Bay). They sat under trees for many yrs and the cabs were rotted badly. The floors and rockers however, are perfect. The bed is also perfect. Had 1/4" diamond plate in it so the wood is like new. Paid the asking price of $800 for the pair - a price I did NOT quibble about!
Intended project is to use the 9' dually bed, along with this 4 eyed C500


And the running gear from this W500


To build one like this


Many spare parts from parting the 2 W300's, including a factory PTO winch and brush guard, go into the stockpile. A person can never have enough!

Plastic trucks suck...
Iron trucks rule...
