The GMC Astro 95 was a heavy duty truck manufactured from 1968-1987. They were the largest cabover trucks ever produced by GM. The Astro 95 replaced the GMC "crackerbox" coe's. These are single sided, and 3mm thick. Very nicely crafted. I copied from my actual Astro emblem which i also pictured. Ive included a few pictures of some of my other Detroit Diesel keychains also available in my store "Taillights"
