Sell the mods to buy a "new" engine, then get rid of the car.
The car will probably be worth more with a running engine.
I know you've been unhappy with the results of your efforts to unload the 'Tour and this must really hit hard right now. However, many have said the mods are worth more off the car and probably only reduce the value of the car.
Just a little unsoliticed advice
I wish you well brother.
