Master cylinder leak

As per title my master cylinder is leaking.
Polaris is wanting $300 for a new master cylinder and not offering any repair kits, imo they’re gouging.
I have the master cylinder out of the rzr and took it appart, it is a very basic cylinder and just needs 4 seals. Its a common Hayes 3/4" bore master cylinder.
Has any one manage to cross a seal kit from the automotive world that will work in this master cylinder. Thx for your help.

BTW it is a 2013 model year.
