I think most of us know where you are coming from. I have been at that point and I kinda am right now. I bought my bronco and got it running/drivable. Then I didn't spend any money. I started planning things that I wanted to do like:
1. 4x4x2 ps
2. Explorer Serpt. Set Up
3. 23 Gal. Tank
4. Fuel Injection
5. Rewire the whole truck
One thing has led to another. I wanted ps but currently do not have it, so I said well I will get the explorer serpt set up for it. Then I found out that the exporer timing cover didn't have a place for mechanical fuel pump. I started thinking about fuel injection. RJM harness went on sale after thanksgiving so I bought it. I had already bought a 23 gal tank but it didn't have an internal fuel pump. So, I sold the 23 gal tank, put more money with it and bought the BCB 23 gal tank with internal pump on DEC31, last day of christmas sale. Wife got me a EZ wiring harness for christmas to replace my body harness. Then it was a little over a hundred for sensors for EFI. Then it was a little over a hundered for frame reinforcement kit and throttle cable from BCB. Another $100+ for the BCB Deluxe fuel line kit. Then I couldn't tell you how many trips to the local parts store for stuff.
Right now I am up to my eyeballs in my EFI conversion, PS install, re-wiring the whole truck, and little things that pop up. I am prob going to rattle can the engine compartment since I have all the wiring harness out, and brake booster out, and while I have the dash out due to wiring, the pedals have some rust on them, so they will get media blasted and rattle canned......
Broncos are Black Holes in our wallets......but man they are fun when we got them running and can drive and enjoy them!
Don't give up Pat. Hang in there man!
