LOOKING FOR ADVICE

Get another cheap later model car or truck to use as a bad weather beater. Keep
the 74 on the road as a rolling restoration.
The OP is rom N. Ga. BAD weather once per winter!!!! ha

For most of us, we need 1 old mopar that is a driver to keep up the interest in the hobby. Drive it and work on it as time and $ allows. If $ and space allow, get a project and tear it down if that stokes your fire. It can be a long and expensive road.
Other solution as already stated, sell the project and buy something more "done" if that is in your budget. Just be realistic in your ability to make a project car into what you will be happy with.
