64-68 Mustang Heater Core w/Extended Tubes

The 64-68 Mustang Heater Core w/Extended Tubes is an essential climate control component for first-generation Mustang restoration and performance builds. Whether you're returning a classic cruiser to original factory specifications or upgrading your vintage muscle car's cabin comfort, this heater core addresses both cooling efficiency and installation flexibility—critical factors when working within tight engine bay constraints on 1960s Ford platforms.

Engineered by Drake Automotive Group, this heater core features extended tubes that provide superior routing options around modified engine bay layouts, larger displacement engines, and custom fuel or ignition systems common in restomod applications. The extended tube design eliminates the fitment headaches typical of original-equipment cores when headers, intake manifolds, or supercharger installations consume space near the firewall. The compact overall footprint (10.5 x 7.3 x 11.3 inches) and lightweight construction (2.17 lbs) ensure minimal impact on vehicle balance while delivering consistent warm-air delivery to the cabin.

Mechanics and enthusiasts restoring 1964–1968 Mustangs will find this heater core indispensable for any project involving engine swaps, fuel injection retrofits, or aftermarket cooling systems. The extended tubes accommodate non-original plumbing runs without kinking or restricting coolant flow—a major advantage over original cores that force tight-radius bends incompatible with modern engine placements. Installation requires proper hose sizing and compatible fittings, but the design flexibility justifies the investment for any serious first-gen Mustang build.
