The Vintage Air SureFit Modified Reduced Barrier Hose Kit (521291) is designed for 1967-68 Camaro and Firebird engine bays that don't have a stock configuration or core support — for example, after an engine swap or custom firewall work. Like the standard kit, it's hoses only and does not include the evaporator or compressor. Each hose has a pre-crimped reduced barrier beadlock fitting on one end, with the other end left open so it can be cut and crimped to fit your custom installation.

FAQ
When should I use the modified hose kit instead of the standard kit?
Use the modified kit (521291) if your 1967-68 Camaro/Firebird engine bay isn't in stock configuration — for example, with a swapped engine or altered core support — since one end of each hose is left open for custom crimping.
What's the difference between the standard and modified hose kit?
The standard kit (521290) has pre-crimped fittings on both ends for a stock engine bay, while the modified kit (521291) has one open end so it can be custom-fit to a non-stock installation.
Do I need special tools to finish installing this kit?
Yes, a hose crimping tool is required to finish the open end of the hoses; detailed crimping instructions are included.
Does this kit include the evaporator or compressor?
No, this is a hose kit only, designed to connect to a complete Gen IV or Gen 5 SureFit evaporator/condenser system sold separately.
Which vehicles does this kit fit?
1967-68 Chevrolet Camaro and 1967-68 Pontiac Firebird.
