Heater Rebuild Kit for 1965 and 1966 Mustangs.

Quickly replace your old heater and its components with an all-in-one heater rebuild kit. All components that normally need to be replaced in a classic 1965-1966 Mustang are included in our kit. Once you install this heater rebuild kit, you'll be able to enjoy driving even on those chilly days.

Features and Benefits:
- Less Prone to Leaking than Brass/Copper
- All-Inclusive Kit
- Stronger, More Durable Heater Plenum
- Provides Consistent Air Flow

Kit Includes:
- Heater Seal Kit
- Aluminum Heater Core
- Heater Plenum
- Heater Cable Set
- Defroster Ducts (Includes Four Clips to Mount Both Ducts)
- Defroster Hoses

The aluminum heater core is less prone to leaking than a brass/copper heater core and flows just as well. All heater box seals are included to make sure air blows where you want it to. The new heater plenum is stronger and more durable than the original to provide long-lasting quality. Air is delivered from the plenum to the windshield with defroster ducts and hoses. Finishing off the kit is a heater cable set. Three cables handle the blower speed, temperature and defrost.

Please Note: Aluminum heater core requires removal or modification of the rubber end caps and the hose placement is slightly different.
