I've heard that the NP203 came on some Fords (77-78?) But didn't it also come on some FS Chevy Pickups? Where's the best place to find an NP203?

From what ive read, it was used by Ford and Chevy in the 70s.

Most (all?) chevy's have a passenger-side diff on the front axle, but i dunno if that makes a difference or not when it comes to doubling them.

Norm, you wanna go Ford/Ford. And not because I believe in brand loyalty (someone give me a 14 bolt please!!!), but Chevy 203s often had 10 spline outputs...........altho I'll admit I don't know the specifics here..........all I know is Ford/Ford is your best bet.

Chevy used 10, 27 and 32 spline inputs, and ford used 31 splines. And even if a ford shaft was swapped into a chevy Case, the mounting pattern on a chevy case is different. So, Keith is right, a ford/ford is your best bet. You'll want to look for a '77-79 F150/bronco for the 203 donor case

I heard they can be found on 70's broncos, but i cant confirm that 100%. Youre probably just going to have to do some hunting in a 'yard.

My D 60 parts truck has a NP 203 in it but from my understanding they are not the best T case . I was going to pull it off but a friend told not to waste my time .

Nearly any year 205 will work, so long as you don't find one with a rear slip yoke (did ford even use those??? I dunno)

A 203 can be every bit as strong as a 205, they just give up space, weight, and long-term reliability (their chains do stretch over time) But since the Lo-range box is all gears, they make the perfect solution to having extra low gears w/o having to spend $1000 + on an underdrive unit

Yeah, but that much doesn't matter. If you find a 203 or a 205 that's married and driver's drop, it'll work. I'd double-check that it's the 6-bolt round pattern and has the female 31 spline input (just so you're sure it's not upside down ;) ), but that's it.

Hey David, did you see the yellow f-100 with the chebbie D60 on the page you linked in your post? I know that guy. I used to work with him at North River Jet Boats. That truck is a rock buggy now.

Yup, that's the one. Arin, I think I rmemeber you telling me that you know the guy, and his stockpile of parts. I think I'm going to have to try to make it down there sometime - preferrably sooner, than later

Yeah I worked with Dale, and I met Justin because he saw the sas in my bronco and stopped to talk to me and get a closer look. Those two have enough parts to build probably 30 trucks. That is why he changed it to a rock buggy. first he was gonna back half it with radius arms and such from the frontend. Then he got a deal on some king coilovers, and to use them , he had to tie the two suspensions together, making the body worthless. I guess there is still like 4 feet of Ford frame in the middle. :shrug
