'93 S83P Fuel level sender / gas tank questions

My gas tank is a crappy rust bucket are replacements available or something close that works with fabrication? If not I'm going to need a fuel level sender regardless as mine is toast. What's available or what works?

Any aftermarket that fits bolt pattern and has 30-230ohm reading will work
