These are a 100% new, factory replacement Tri-Five heater core. Not a marginal recore like others sell. For '55-'56 Chevrolet cars without factory air conditioning. We also recommend the mounting plate, which is normally rusted beyond use.
Note: General Motors produced two different style heater cores for these vehicles. The heater cores we carry are a reproduction of the "deluxe" model, not the "standard."
Length of main core and tanks is 10", Inlet tube adds an additional 1/2" to overall length and so does one mount bracket. Width is 7 1/4" and thickness is 2 1/2". Inlet and outlet are both on the same end and pointing in opposite directions parallel to the core. One extends 2" past the core where the other makes a 90 degree turn ending mid way to the width. Both inlet and outlet are for 5/8" hose.
