1966 Impala 11" heater core
I recently blew up my heater core. I ripped my dash all apart and got the old one out and picked one up at my local car parts store. When i got it home, i found that the old heater core was 11" and the new one was 9.5". i have scoured the internet looking for somewhere that sells an 11" heater core for a 1966 impala: it keeps telling me that the 9.5" one is the right one. It is not. the brackets will no longer hold the new one in as it is obviously 1.5" too short. The car is a canadian car (if that makes any difference).
Has anyone ran into this before? Is there a proper 11" long one available? Can the 9.5" be made to fit? slightly frustrated. any help is greatly appreciated.
