Reviving a very old thread, not much activity around here but I'm not sure what advice to trust from what I'm getting from Facebook and the like.

Have a '68 WITH Factory AC - leaking heater core, it's dripping on the passenger floor mat.

I have read through this and other threads, most seem to be replacing on NON-AC cars.

My main question is can this be done in similar fashion on a Factory AC car, without having to completely pull the hood/fender and inner fender? I think I can get the inner fender support bracket off if that helps access. Really don't want to have to pull all that sheet metal. But if I did, believe me, the heater core would not be the only thing replaced, on preventative grounds alone.
