I have a 69 coronet with original lines throughout. It’s a manual 4 drum car that I will be converting to a front disc and keeping the rear drums and probably putting a booster on it also. My question is do I go through the trouble to replace all of the hard lines on the car or just reuse and see if they work
Keep original hard brake lines out replace?

Maybe try flushing out from an easy spot into a clear glass container.
Take a look at the fluid it might help you make a decision.
I would suggest replacing any rubber lines at a minimum.
But it's almost easier to replace everything with new than just pieces of the system.

How corroded are the lines on the outside? As Don mentioned, looking at the condition of the fluid can tell you a bit about internal rust. At least, before taking everything apart, simulate a panic stop by jumping on the brakes full force (you don't have to be driving, the car can be stopped). If there's a weak line anywhere, that's when it will leak or rupture.
They aren't real expensive just be careful about the line that runs across the firewall to the front passenger wheel.
Sometimes these vary from car to car so make sure you order the correct style.

Replace them. Why take a chance?
DOT 4 brake fluid loves moisture. Pour some on the ground and wash it away with the water hose. I don't use it anymore. Yes, just replace all of it. One of the first things I did with my cars, brake and fuel system replacement.
