[Bob/Kansas City]

When I reinstalled the rear fenders on my town sedan I just mounted the fenders fairly loosely and then slid the tab of the welting in between the fenders and the body. Be sure to make some V shaped cuts in the welt tab to allow it to conform to the curves.
As I drew the fenders up tight I kept pushing the welt in until it was held firmly in place. I did use some spray adhesive on the dog leg at the front of the fender where it meets the splash apron because that is such a tight turn there was no other way to hold it in place when mounting the fender.
