I have a 1969 C20 that came with a/c... which was yanked out a few years ago and have no interest in putting back in. I need a new heater core but before I start buying parts I'm curious if the firewalls on all models were the same. Would love to get rid of all the a/c related parts and make it look like a non a/c truck. Plus I have access to a non ac truck for parts.
Thanks
