Dodge FOR SURE used the NP435, and a few sourses state that Chev. used the NP435 as well (old & rare). Dodge used lots, I even have one (23spl output).
Heres your 'sweet' set-up. Dodge NP435 adapted to a Dodge NP203 gear box(stock pieces), then adapted to the T-case of your choice. D300/NP205.
All ya need is 1 adapter, and 1 shaft shortened & splined.
Overall I'ld say pretty cheap for a doubler set-up & 1:1,2:1,4:1 gearing.
22 3/4" from back of bell housing to end of NP203 gearbox. 11.5" for a Dana300 & probly a 2-3" adapter.
Dana 20 = 10.5"(1 more inch shorter)

Chevy NP205's have 2 different female spline counts 27(TH350) & 32(TH400). The SM420's use a male input(10spl.) w coupler, I 'think' the SM465 uses a female input in the later trannies/T-case combos.
Ford NP435's have 2 different male spline counts 28(2x4) & 31(4x4).
This is why U need the Ford input(to match the Ford output).
The Chevy NP205 will NOT bolt directly to the Ford NP435. Chev & Dodge use an hour glass type bolt pattern, Ford uses a circular bolt pattern. (It can be done tho)
This would re-use the stock Ford NP435 to NP(whatever) adapter which is 8 5/8" long (I think there is only 1 size).

The Ford(4x4) & Dodge NP435's have the same case.
Use your Ford NP435 & put a Dodge output shaft into it, and bolt a Dodge adapter to it. It's shorter & 23spl. Using the Dodge junk re-uses all stock(accessable) pieces and is 2 5/8" shorter.

Or use a full Dodge NP435 and bolt your bellhousing to it instead of changing your output shaft. Same shit, less work.
The bellhousing bolt patterns look the same (I'll know for sure tonight, cause I'm pullin one off).

?!?!WHATS ALL THIS CHEVY TECH DOIN' IN THE FORD FORUM!?!?

what do you guys know about the Ford 4-speeds with OD that came in late 70s early 80s F150 and vans?

A four speed with overdrive? You mean just like a 5-speed?? :flipoff2: LOL
Longer, lighter(aluminum), and not as well proven IMO.
I've never realy looked into the 5-speeds as they are too long for my app. (& I drive my junk hard).
With the low first gear of the NP435, I'm goin with higher gears in the pods to get some speed outa my land sled.
If your goin 5-speed(O.D.), look at NV4500's

THE BELL HOUSINGS ARE DIFFERENT!!
The 'spread on the Dodge bell is 2 5/8"
The 'spread' on the Ford bell is 6 3/8" (but can be changed).
The Ford NP435 has a place for the bolt hole to be drilled in it, the Dodge doesn't.
So use the Ford case with the Dodge output in it.
Plus the support / leverage would be WAY better with the bolt holes being 6" apart, compaired to 2.5" apart.
I got some pic.s if someone wants to postem.

I'ld guess it wouldn't have a 'bull low' first right??
Cause if it does its a 2 speed with overdrive(know what I mean?)
The spread must be pretty huge.
I'ld see drivability probs with heavy trucks & smaller engines. Need power to compensate for the spread between gears.

City driving = leave it in first gear
Country driving = leave it in second gear
Hiway driving = leave it in third gear
LOL
