I remember the helicopter kit, never saw the Blazer kit. As far as these kits, I have the original GMC pickup and Blazer (missing the mirrors, but complete otherwise), the 90s reissue of the Chevy pickup, and Madd Mudder. Looking forward to the upcoming reissue of the GMC.
Another Monogram pickup of this era is the Snap Tite GMC tow truck, which was recently reissued...I have the '90s issue of it, one thing I didn't like was how the windshield shade was molded in place.
