Recently i purchased a used camper shell for my Toyota truck. I'm not sure what truck model it was designed for but it doesnt quite fit. The length is perfect but the width is too wide. I have a 2 inch overhang on each side. I've been thinking of cutting it lengthwise and removing the offending 4 inches. It is a mass produced fibergalss camper shell and i'm not sure what kind of glass to use to "weld" it back together. It appears to use a heavy type of mat or roving. Any suggestion on what would be a good type of material to use???????? Thanks in advance. P.S. I purchased it used for 60 bucks, locally the new price is $1200.00. So if I dont do anything it still does the job.
