By the time your finished with that thing you will be broke and still not have a good Jeep.
Go into debt and buy a newer Rubicon and have a much better vehicle you can enjoy right now instead of working on and throwing money at for the entire time you own it.
Ask me how I know that. I paid $600 just for a T 18 trans 15 years ago, and spent lots of hours scraping the grease off and cleaning it, then paid to have it installed. Just one of the many many items I wasted my money on.
