1969 Dart factory AC value

[Mopar4ever]

We’re doing a drive train change in my sons 1969 Dart and I’m wondering what the factory AC is worth? The only item I plan to re-use is the evaporator- everything else would be sold. Compressor turns over and everything looks good, but there was no pressure in the system. Any thoughts?

Thanks for any opinions.
