It might be better to find a tailor/repair shop. I lost a favorite pair of ski pants when I sent them in for azipper replacement. Not sure if something got mixed up in the paperwork but I requested they be returned, not replaced if the repair was too expensive/difficult. The pants I got lasted many more years but the others would have too. Unfortunately zippers are just hard to replace if the teeth get damaged. They tend to be sewn in early in the assembly process.
