I heard about the GMCs near Streeter several years ago and spent a Sunday afternoon looking for them. I never did find them. A lot of 50's GM trucks came through Fredericksburg last year that had been crushed and were going for scrap in SA when scrap iron got so high. We are the Fina distributors here and a lot of them stopped at our place out on the SA highway because it is the nearest thing to a truck stop around.
