the np435 is directly bolted to the bw1356. i cant say if it is useable for your application.not knowing what your final stretch is or if you will stay stock in wheel base.i allways mock engine and trans/transfer up in a bare frame .block and support it then sometimes rough set the tub on .measure and ,measure make some marks for the mounting with a paint pen or soap stone.dissmantel and temp tack engine mounts in and refit.full engine trans transfer install with body on is going to be a little tricky.i believe the bell housing from a ford straight 6 300 will bolt directly to your 302 you still need the flywheel / clutch assembly .a 1inch body lift will help with bell housing clearance.dont start fitting till you have the complete assembly (engine bell housing trans and transfer).This transfer case is chain driven, and has an aluminum case. It's pretty similar to the NP208 in those respects, as well as the fact that it has the same 2.72:1 low-range ratio. Ford started using this in 1980, and discontinued its use in 1988, when it was replaced with the BW 1356.


Ford Borg Warner 1356
The 1356 was first used in 1988 or 1989, replacing the BW 1345. Like its predecessor, it's chain driven. However, it has a stronger, magnesium case.


The 1356 is available with or with out fixed yoke rear output

The measurments I gave you are from a 1356 that is married to a T18.


I am unsure if or by how much the length of the spacer/mount between the transmission and transfercase varies.

Just checked measurements on the jeep now....
AX15 approx 24.5" from bell to rear of trans where 231 bolts to. 231 tcase measured approx 16.5" Total would be approx 41"
Np435 bell to rear of trans is approx 17"
My math says I have 24" of tcase & whatever spacer are between the case and trans. Plus a few inches I can move the motor if needed.
BTW motor and trans are from a 86 F250 complete from fan to the rear of the trans...bell, clutch, slave ect..plus 2" body lift and 4.5" suspension

I have been searching for the Ford hydro bell housing for about 3 weeks now, It seems this bell housing was used in a diesel app and is failing so those guys are jumping on them. I did find one on eBay but $400.00 just for the bell housing with slave cylinder bracket.
I decided to stick with my mechanical setup with a non hydro Ford bell housing.
I have a Ford 302 with a T-4 and trying to be prepared for the inevitable. I think I am going with a T-18 from a 70's CJ that will be a direct bolt up with only drive shaft mods and possible shifter relocation in the tranny tunnel.
Good luck and let us know how it turns out.

Are you planning to get the d20 with that cj t18? Because it won't bolt up to your D300. If you want to keep the d300 then a Ford t18 would be the way to go. Can usually find then much easier and cheaper than the cj version and either will have to be adapted to your current tcase

the ford small block bell housings for the 289 300 302 351w DO NOT FIT ANY FORD DIESELS. diesel bell only fits 6.9 and 7.3 navistar idi style diesel. the small block bell is a dime a dozen in hydraulic style.2and 4 wheel drive trucks and vans with 300-351windsor motors will swap direct to your engine. the diesel bell has cracking issues from torque .ive tig welded these bells with success many times. go hydraulic clutch if you can. i probably have one or two sb bells in the bone yard out back.if someone is lookin for one. a good site for ford info is fordtruckenthusiast.you will find all you need for info their. many of these bells are broken during install and removial .people just cant resist drawing engine and trans together with the bell bolts or do not support the engine and trans transfer properly when dissassembling.

Does anyone have any measurements of the np205 and bw1356 & adapter in between the trans (np435)
Im trying to add everything up. I have a total of 41" from bell to tail of the stock driveline. Np435 is 17" to the back of the trans so l have 24" to got till I am at factory length...plus motor can be moved forward a little so I can still end up with a longer rear shaft than stock. Np205 seems to be 12-13" from what info I can find. I need a total length. Shaft sticking out of the back of the trans....not sure what length adapter is needed or available. ..

just curious....why not adapt the AX-15 to the 302...?
AX-15 should handle a even a moderate 302 and you would have 5th gear... such a blessing for MPG and long trips.

the np 205 is a great transfer all gear driven but dont forget it weighs close to 250lbs. so you need a crossmember just for the transfer exclusivly. .. Or run a 70 era 435 and 205 setup.any late 70's f150,250,350, or bronco run this from factory with a adapter to marry them.. You can get this adapter from JBG for $45-65 to run with a 4wheel drive version of the NP-435, and it can be found in a junk yard if you know where to look.This setup will work it will fit .just got to think out of the stock box.

They say 138lb...
Motor and trans are out of 86 f250 90 motor.
I dont like the added weight or the 1.98 ratio but strength of it, twin stick capabilities and probably the length should work.

Granny gear in the np435 (6.68) is the decision maker... but np435 is much stronger than the ax15 (3.38or around there 1rst gear) plus my slave is bad and its the internal one.. and the adapter for the 302 is as expensive as the motor and trans cost me. Ax15 also does not get me a fixed yoke. Ect...
Over all the driveline will end up solid as a rock except the rear that I'm sure I'll break:-)

40dog...was that to me?
My name is Rich :-)
I did do an xj case last year in my yj. I notched the skid plate and it was working fine. I put it all together with the ax15 upgraded from the ba10 but the fact that I did not get everything and do the external slave which proved to be my demise. So rather than do the same job again with the same turd 4.2 im just doing it all with the ford stuff. Once I get it done it will be worth it all.
