I think it was E P Barnum who said,(theres one born every minit) lol.
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.
New Rubicons are close to $60k!!! At least that's what was on the one I looked at at the dealer last Saturday. Instead, I bought a super clean 2006 Rubicon for $14k. Nice part about it, after I got it home and begun crawling around underneath it, I found it has a Dynatrack 44 front axle which (according to the Dynatrack website) start at $5100 and go up from there depending on options. It was nice to find that jackpot lurking underneath!
As for swapping in a T-18 into my '78 CJ5...I took the easy way out and had a 4WD shop do it. All up it was $900 out the door...of course, this was back in 1990!!
JEEP = Just Empty Every Pocket!!!
