Bubsy, there is a slight "channel" that the welting fits over. I cut 3/8" strips of 1/16" rubber, about 8" long and placed them under the welting to shim it up. Also, when you do the installation, at the bottom of the radiator shell there are three vertical slots that accept the lower welting attaching clip. Size the welting to the top slot. This allows you to tighten it as it stretches. If you don't have you car "fine point judged", let me offer another tip. I used 3/4" shrink tubing at the ends of the welt. It really cleans up the raw edge of the welting and prevents fraying of the material.
