Unless I am mistaken you can confirm JPS by measuring the width of the rear brake drums.
The FIRST thing to do with this car is to get it clean!
Then Carefully check the engine out, TC's are not cheap to rebuild.
DO NOT try to turn it over until you have vacuumed around the spark plugs to prevent crud getting into the engine.
Pull the plugs and squirt a mix of Diesel and Marvel Mystery oil into each cylinder.
Let that sit for at least two days.
You need some cheap roll-around tires put on, just something to make it roll well.
You can get the Toyo R888's later.
Once you have good tires and the oil has had a chance to work you may put it in gear and rock the car forward and back a little at a time to see if the engine turns over at all.
If it does you may fit a good battery and see if it cranks smoothly.
This WORKS!
I freed up a Jaguar that had sat for thirty years this way and got to drive it the next day.
I cannot tell, is the wind$hield good?
Bumpers are not cheap to get chromed, I just did that.
A less expensive option is to buy new stainless bumpers.
From what I am experiencing even the good looking cars usually need a body-off restoration unless that has been done recently.
I have proof of that in my shop.
Ugly paint is nothing, bad repairs and rust are a PITA.
Your biggest advantage with this car is that you already own it.

Custom beauty is in the eye of the beholder. But from what I have observed "Custom" always has more value to the customizer than anyone else.
If resale value is important leave it visually stock, maybe add a little performance.
Several threads on this forum caution that for street use wide tires actually hurt handling.
It is yours so you may do whatever you like, at least you are not asking about an EV conversion.
