Put heat and rubber together and you have an assembly that requires periodic attention. This kit includes all the seals you need to put your heater back together again. If your heater leaks, then it's time to rebuild it with these quality rubber seals. The kit does not include the defroster seal. Fits all 57 Chevy models with a Standard heater.
