Just stumbled across one of these late '70's parts packs. This one isn't 100% complete, but I figured a few of y'all might be interested in seeing what's in there.
The instruction sheet... say, doesn't that look like an MPC Dodge kit? There's also what appears to be an AMT '72 GMC kit on one of the box side illustrations... as far as I know Revell never did a late '70's Dodge pickup or a pre '72 GM truck.
Two stepside beds- one for compact trucks, the other for fullsize trucks. The hood scoop is also on this sprue.
Wheels, flares, rollbar, and bed cover. The bed cover is scored at the bottom, you use it as-is for the fullsize bed, or cut out the scored part for use with the compact bed. The wheels are dinky- about the same diameter as Revell's modern Lowrider kit wheels.
That giant grid is the custom grille material. There's enough here to do at least three trucks. The custom quad headlight bezels look an awful lot like '66 Olds pieces. All lenses are chrome.
Wheels, lights, bumpers (again differing for compact and fullsize trucks) and winch. As with the non-plated wheels, the plated ones are a bit on the small side.
