I have a mint condition 65 Riviera, and im trying to get the heater
core out because it decided to leak all over the carpet. Anyways,
I cant pull it out on the engine side....do i have to take the
dashboard off, or can i get it out from under the dash somehow?
So far it doesnt look like i can get it from under the dash, but i
wanted to know if anyone has any ideas....

the only one that i have done was a full removal of the dashboard, as much of a pain as it seems, its better than damaging something while trying to cut corners.

yeah, thats what i figured. thanks for the info.

youre welcome...good luck!
