My truck is a 1953 Chevrolet 3600 3/4 ton . It was supposed to have 2 degree caster shims installed. If your truck drives and steers perfectly. You don't have any issues on the wandering issue. I do!!
Check your truck manual, It will tell you what you need. The shims are stamped what degree they are. Again, If there aren't any issue with your steering. I wouldn't worry about it.
