Man !! I don't know how you get involved in the hobby at 15 years old!!! I wish I could turn back time... I am 35 and am a proud owner of a GPW.
I remember, being a kid, seeing a movie or serie on tv where a couple of kids were stucked in some kind of forrest in Australia or pacific. One group of kids found an amphibian truck (a DUKW) and they painted a large mouth with teeth on the front and they drove through the forrest and scared the hell out of the local bushmen... which they thought it was some kind of monster/dragon.
I have no clue what kind of movie/serie it was, but it was for sure a movie for children. Maybe somebody here remembers it... I think it was broadcast in the early 80's.
Keep up the good work... the DUKW is one of my favorites. Maybe you can make a list of special DUKW parts you need. We have several large dealers in Holland who might have lots of parts for the DUKW too...
