This is a set of hood lace hooks to be used with the hood lace with wire insert that was used on most GM vehicles from 1929-1939, including all Chevrolet cars & trucks. Each hook is designed to grab the wire that is inserted inside the hood lace and draw it tight to insure a clean installation. These are an exact match to the original hooks. They have a threaded shaft and come with a nut for tension. Replaces GM# 355568
