Nothing sucks more then breaking a zipper tab on a leather race jacket. Replacing it is a hassle, it's security stitching and needs to be sent to the factory. With no tabs, the locking mechanism locks the zipper and it's impossible to bring up or down without fighting for your life with the zipper.
So. For 1$ I bought one foot of 1/16 steel cable and aluminum clamps found in the same isle.
It took a pair of vise grips and wire cutters and about 2 minutes.
