These are for many different types of military trucks and are about 12" long. They are for the drop gate chains and these are the newer heavy duty vinyl and they don't fade as fast as the older canvas ones. I got some sets on a recent trade and I have three (3) sets of two (2) that I will sell. I am keeping some for myself but will let these three sets go if anyone can use them. Each set of two is $25 shipped, USA residents and address only.
