This listing is for one new AFTERMARKET replacement heater core assembly.
from Swedish Car Parts. The heater core is the same size as the original, & has a foam rubber seal attached around the perimeter of the core.
Our heater core will fit the air box cavity without ANY modifications, and you DO NOT NEED extra strips of any kind of padding for RATTLE PREVENTION.
This is a correctly made part. No holes needed to be drilled, no extra screws to hold the part in place... Nothing.
