A/C - rebuild or replace?

[DylanVK]

My '67 is an original AC cab truck and the controls are all in excellent shape/working order.

Currently if flipped on it blows slightly cool air, but the compressor has some squeaks and other obvious issues. Should also mention its R12... havent even looked into how I go about dealing with that yet.

Looking for opinions if its worth rebuilding the setup thats on the truck now or just gutting it and replacing.

To be perfectly honest I enjoy driving this thing with the windows down too much to run the A/C very often anyways, so this would be more for my own piece of mind knowing everything works perfect if I should ever decide to part with it.
