 In Process of LX to GT conversion
It's a big project that's for sure. I recently finished taking the donor car engine, transmisson, suspension, and engine wiring harness with computer out. I have my engine broken down and am cleaning, and replacing parts, gaskets, etc. . . Give yourself time. I began working on prepping everything early November, and began som Libo to do the project, total of 30 days is what I estimated. So far so good, but that is non-stop work. If all goes well and I don't have any issues I should be up by New Years with my new 1990 Mustang 5.0 GT. Because I will be gone on Business for a long time I made the choice to bring te car up to a touring style so that it's drivable. Later on I will start placing nice stuff on her.
Start with the basics, ensure that you have a good frame, and structurally the car is sound. The cowl (grate in front of the windshield) is a rust magnet. This piece is spot wielded in, and is a pain in the butt to fix. Check the areas around your door hinges, My donor car had severe rust damage there, and my LX has minor damage that's easily fixed with some POR 15.
A cheap donor car for parts is handy and saves money. Research your parts, don't just jump in. You may find that some places have better prices then others. There's a place on Oahu that marks performace prices sky high. I didn't realize this till I began researching parts on line. I will not go to that place anymore.
Take lots of pictures, before, during and after. This is something I wish I would have done. Looking back I could have pulled the pics up and used them for reference on how certain parts fit, and where they go. Bottom Line Up Front (BLUF) document your steps some way. Bag and tag all your parts too. It will take some time but the pay off will be less headaches when it comes to assembly time.
Invest in who ever makes sandwich bags because you will use a lot for bagging and tagging parts. Foil works great for covering wires and other stuff when your painting.
Break clean in spray cans works wonders with cleaning dirty greasy parts. A nice pressure washer also helps too. If you can get a hold of a can of "Strike Hold" it works wonders with rust. It's sold mostly in gun stores, google is a good way to find a dealer.
Plan ahead, and make sure you do your research. Read the thread, and forum. There are a lot of great pieces of wisdom. I very much the novice on this and constantly look up new information on this project.
Lastly have fun, and enjoy the time you got with your father doing this project. Working for something / buildin something always puts more personal value to something.

It was a much more involved job than I had anticipated. I do not have a working tempature gauge and the oil pressure only reads to the first mark from the bottom. 
I also don't have any air coming from the center ducts. (I pulled the dash when changing everything over) How do I trace that down.
