Possible to re-upholster 4th gen leather seats>>>>?

Hey guys. I am buying a set of black leather seats out of a 97. Got an excellent deal on them. The rear are mint, but both the fronts have a large single "slash" in them. My guess is someone did not like the owner. Anyway, I am getting them cheap because of this, they are otherwise unblemished. my question is how much would it run me to have them fixed, if it is even possible. I really want to just fix them because they are great seats otherwise. They are the current, LS-1 style seats. If anyone has any input, please let me know! Thanks

Will
