Probably wrong forum. But, I seem to have noticed, by the posts on this site and other GMC sites, that most everyone is working on the 1940's to 1954 model stovebolts. Don't seem as much interest in the 1955 up models. Guess it's just a fad that vehicles go through. It seems in my younger years the 55 and up were more popular, especially since they did not have the enclosed driveshaft. Just a thought.....
