Small update and question.... no headlights. I hate wiring issues which I think it is. No fuel level. So need to research the sending unit in the tank. I assume its rusty from sitting empty. Next. Once it gets driven for a while it does not want to go into first. Is that typical of an older granny geared 5 speed or is that the sign of a problem?
No headlights, first thing I'd check is the floor mounted dimmer switch. One wire should be hot whenever the headlights is on, the others are high/low. They corroded bad from wet shoes stomping on them over the years, if that's good you'll have to trace it out with a test light.
Fuel gauge, un plug the sender wire, ground it to frame gauge should go full, if so wiring and gauge are good problem is in tank, these had a brass float that will get a pinhole like a carb float. Ford should still have the float for $20 or so. It fits pretty much every Ford car or truck pre 1992ish. If the gauge doesn't move post back up and I can walk you through testing the gauge and instrument cluster voltage regulator.
And no the trans should not be hard to get into gear hot vs cold. It should shift the same all the time.
