Replace this tank?

What's it out of?

How hard is it to get another,?

Make some plugs

Put 5 psi in it and see if it holds pressure
1974 Plymouth satellite Sebring plus. Not too hard but about 400 bucks. I’m not in any hurry. I’ll probably be welding for about a week in my spare time.I think it’d hold 5 psi fine, I’ll try that.Thanks man.
