The neutral safety switch has nothing to do with shifting out of park.
It's been 35 years, so my memory could be faulty, but I thought the brake switch to shift out of park started with the 1992 models.

Try this: Turn the key one detent towards run, but not enough to turn anything on. Now see if you can get it out of park. If you can, the lockout is keeping it from shifting. That could be due to a bad switch, or a bad brake light switch.

This Umm custom rv has had the original ignition yanked.They installed a screwy push button.O may just run a temp jumper and see if that flies.As I know it will keep the lights on.The part in question is $30 but there let's say ( struggling) money wise Have a ton work so, I may pony up and buy the part.

Often, people live in older (this is a 35 year old unit) RVs when they can't afford to live anywhere else.
