The silver thing at the top with the screw sticking out looks like a fuel pressure regulator. It looks like there's a fuel pump just under it.
These aren't bad parts, but they're in a bad spot. The pump should be close to the tank, but the regulator is typically in the engine bay to make it easier to service. If it's a bypass type, you can use it to help prevent vapor lock, but I bet it's not doing that the way it's installed right now.
A handy csr guy could probably have that car near perfect in a couple hours with no new parts..
The lokar cable setup is probably your biggest hurdle. I've never used one, but lots of members seem to find they can either get the trans cable right, or the throttle right, but rarely both.
Lots of people have stuff to say about the costs you've paid, but those are pretty average these days if going to a shop. Fee are willing or able to swap in an OD trans but are quick to criticize when someone else pays to have it done. Makes no sense. It's a shame the one shop went out of business since the benefit of paying a shop is having someone to hold accountable though.
The car is really close, and others are right: a good running car is going to being a premium over one with issues. I'd be tempted to try bring a trailer. Buyers there seem to like giving away money these days and a real demon in good shape is tough to find. Lots of reasons not to sell there too though.
Best of luck. Hopefully the next mechanic has a soul!
