Police Interceptor Heads?

We all know about the 2 I believe 78 Little Reds that had 440s in them.
In my years of Moparing I have heard the story of 2 w2 trucks. One went to a 4x4 race team in calif and the other disappeared and was never found. Have you found the missing truck?
That would be super.
The 4x4 w2 engine as the story went was pulled from the truck and put in a Duster I believe.
If you don't know about the 440 Little Reds I have a copy of the letter about it.
