ok little confused on my NP435. ive been reading there is a difference in shaft length between a 435 that was bolted up to a 205 or a 208, if true what do i need to do since my NP435 came from in front of a 208. i have the spacer or sleeve or whatever you call it from in between the tranny and t-case from the 208 setup. is that the one to use for the 203 or do i need to use the one from a 205 setup or what?
another question. the np435 will sit closer into the dash since it doesnt require the spacer that went in front of my t-18?77 cherokee chief 360/435/205-60/60-42's

What is the measurement of your 208 adaptor to compare with?
The NP435 205 adaptor is 8 5/8" leaving 3/4 of 435 tailshaft stickout (edit, both of mine are the same). I'm not sure if the 208 adaptor is any different... if so I'd bet you want the 205 adaptor as the 203 is more similar to the 205 at the front of the case then the 208.
It will put the tranny closer to the firewall, but the shifter is already bent different to clear a Ford dash. Can't tell you if it's knuckle basher yet, but you can always heat and bend it back a lil if you need to.
Edit, Both the Ford and GM pattern cases locate the input gear in the same location respective to the back of NP435 adaptor I have. The NP435 tailshaft has 2.5"s of spline length and sticks out ~7/8" past the end of the 8 5/8" adaptor. The 31 spline input sticks out of the case 1 1/4" and has internal spline length of 3". The total spline engagement with this set up is ~2 1/8" with the gasket in there.Last edited by Elliott; 11-26-2006, 09:28 AM.*** I am collecting pics and info on any factory Jeep Dually trucks from the J-Series at the new Jeep Dually Registry.

LMK what you measure for you NP435 tailshaft and adaptor.
My tailshaft is ~9 1/2" overall.*** I am collecting pics and info on any factory Jeep Dually trucks from the J-Series at the new Jeep Dually Registry.

Ah, but you are going to miss all the fun of stripping/rebuilding the range box to redrill the front of the case

I have some sort of np203 gearbox floating around here, i'll try to dig it out from under the bench and check it out. If its a 32 spline, i'll let you know Nick, I have no use for it at this time. I'll probably go Klune if I decide I need more gear.Brad W.

crossmembers
moving forward on this doubler. what would everybody do for the crossmember to support the 203 and 205? could u reuse the 203 or 205 doubler, drill and cut it to mount to the frame and go on with life or whip out some round or square tubing and fab one up? do you need two crossmembers one for each tcase?77 cherokee chief 360/435/205-60/60-42's

Brad, if the adaptor is still bolted to the front of that GM203 and it only has 4 bolt holes for the transmission it will be 27 spline, if there are 6 bolt holes for the tranny it's gonna be the 32 spline.*** I am collecting pics and info on any factory Jeep Dually trucks from the J-Series at the new Jeep Dually Registry.
