No, you can't do it. We won't let you start another project! Stop now!

But seriously, why the T-18? Why not go NP435? If you snag this setup, which is designed for the front axle on the "wrong" side, you get a lower first. Oops, I forgot, you already have the T-18, never mind. You'd need an adapter, then one for the NP231. You might do better to find a NP435 setup, they should be cheap. While I have never heard of anyone doing this, I'm sure you can get the adapters for it. Nice jeep, BTW.

just my $.02, and everyone who knows anything knows not to listen to me but if you plan to use the jeep as a dailly driver you will probally end up killing yourself. the t-18's 4th gear ratio is 1. This works fine with the 304 and 258 that it came with from the factory but with a small 4-banger you might have some speed problems.

Hey Kev,
Came across this today and remembered you...
http://www.jeeptech.com/convtrans/sm420yj/

Now this is for an SM420 but heres what I am thinking. They are using a chevy bellhousing. I know a chevy bellhousing can be modified to use a ford tranny. So mabye it would be possible... And I saw a post on the Jeep Wire BBS where someone is doing the same type of thing with a Ford NP435. You might want to check there too. Its in a post about putting a SM420 into a 4cyl TJ on the jeeptech board.
Heres a link:

I don't understand what Jeepn is saying about the axle on the wrong side. The transmission to transfer case adapter isn't the problem. It's finding a way to adapt the tranny to the bellhousing. The same problem exists whether you're talking T18 or NP435. I would go with Mark's suggestion and try Novak. They are more willing to talk straight about what can and can't be done even if they don't carry the right parts.

You might want to call Hicks for that adapter. I know they have a lot of different stuff than AA.

thanks for the info guys

if the T-18 cant be mated, I will stick with the stock AX5 until it blows. I already have the T-18 and dont want to deal with trying to get something else.

I will research this some more and let ya know what i find

thanks

Whay I was referring to was the fact that his T-18 is setup for use with his Scout II axles, which have the front pumpkin on the passenger's side. His current setup in the YJ has the front axle pumpkin on the driver's side. So even if he can throw in his current T-18, the transfer that's attached to it (the D20) is not setup correctly. A regular T-18/with transfer from a Ford would work, but this current setup won't.
