That is actually a re-issue of an older kit. Still a awesome kit though. It was previously released as the "Fall Guy" truck. The Brown GMC from the TV show. You can just see the line in the bed just behind the cab that was for an access door as it was on the show. Funny thing is the truck in the show was a longbed and the kit has always been a shortbed.
Should be available at most hobby shops everywhere. That is if there is a hobby shop near you. They are a dying breed just like good local parts stores (not autozone)
