Right, Tim; the trouble with '55.2 & '56 similarities is the same trouble I have with '55.1 & '55.2 "differences".
There are blurred lines in what the
factory considered "factory" at the time. And I'd bet my truck those fellas that worked on the lines are having a blast laughing at all us trying to figure it out!
A known fact about my 55.2 tailgate: my great uncle hand painted the letters onto the tailgate with a white color paint.
In my restoration process, I hand-sanded the white letter paint off, through the re-painted green (he painted it hunter green), reaching the original Neptune green paint. No evidence of any lettering between the original green and the re-painted green.
(My cousin also remembered him painting it, & told me about it

)
So...I also know very little about Task Force trucks- I only know a lot about mine.
