Ok, so a little back ground. I put together a 1970 DJ postal Right hand drive Jeep. It had a 4cyl Mercedes diesel/ax15 5 speed/dana300. Well after a lot of money and time, the Jeep wasn't practical because its a postal basically. Skipping a lot of detail...I knew I just needed a newer jeep as a starting point and knew I wanted round headlights lol. Don't tell the YJ guys I said that! Ok on with my post!
My basic goal is to have the transmission back bone stock. I have a 4cyl ax5 now. So I am stealing the ax15 and adapter from postal jeep. I have a om617 5cyl diesel. Some questions I have are:
Is the transmission cross bar the same between 4cyl and 6cyl models?
Is the driveshaft the same between 4 and 6 cyl models?
About the transfer case.....NP231...my 4 banger won't work correct?21 vs 23 spline right?
Any other thoughts are always welcome and if you know of someone or someone on this board that has done this diesel swap, let me know please. Just have random questions. Ive been down this road with my last jeep but any helpful insight just saves time. On my postal, I had no help and everything was trial and error since no one had done it to a postal jeep. Figure this time around id rather not reinvent the wheel
