Here's a pic of the parts included only in the '77 Boonie Boss/Matchbox Ranger editions from this series....
The blue sprue is from the Matchbox reissue (F350 Ranger) of the Boonie Boss. As mentioned above, the BB and it's reissue also included a modified front bumper with provisions for mounting the push bar and driving lights.
The following are pics of the main unique parts in the Tuff Truk issue. It also had a full width louvered rear window plate and rear dual wheel spacers.
