I have Tom's Bronco seats in my 1976. The rear fold and tumble seat had a bracket inside break off for the headrests. For me to weld it back on I need to pull off the cover. The bottom of the seat cover has zippers but no actual zipper. Its open on both ends, but zipped closed. So I figure I can unzip it to access the backrest frame to weld the bracket back on however, I am trying to figure out how to zip it back up with no zipper. Anyone know what size zipper it uses or have a better way for me to access it?
