For sale at auction: Lot #1595 - Here is one of the rarest Mopars in the auction today. This is a 1977 Dodge Power Wagon that was special ordered from the factory with a Worlock package. We have the original equipment ID sheet to prove it. This is more or less the same as a build sheet from this year truck. From research that was done it appears to be 1 of 4 ever built. The owner wanted a Worlock but wanted a bigger motor, and 4x4. So this was special built. California original, very rare, 440 engine (original) new transmission, 4x4. Own one of the rarest Mopar's on the planet with documentation.
