I found a 1973 2-door 98 big block ready to ride recently. Now its got a leaky heater core. I've removed the bottom of the dash and some screws from the housing where the core is but now i'm stumped. Anyone out there have any experience on this? Any help would be appreciated. Thanks!

 

i am not sure, but as intricate as that may be, i would look into a shop manual for it...perhaps a chiltons...

 

did you look in the engine bay. my olds has some nuts on the firewall. i think i had to take em out when i did my core.

 

I found the rest of the screws, Thanks!
