69-71 AC heater core

[hath]

Hi guys, does anyone have an old 69-71 F*** AC heater core and heater box you'd sell me? I want to see if I can reman those cores. But need originals first for reference.

Correct me if I'm wrong on years.

Also, if you know of any other obsolete heater cores, let me know and I'll try tracking those down too. I'm told 1964 f100 heater cores are obsolete? And specific to that one year?
