Early Bronco T-case

Ok Iwas wondering....What kinda dana 20 is better? Either the t-shift style, or the j-shift style? Or would u recomend me to run a different transfer case from the way back era. I'm trying to runna and NP435 to a t-case

The t-shift and j-shift are pretty much the same. The t-shift is geared slightly lower at 2.46:1 vs the j-shift at 2.34:1. The j-shift is slightly easier to twin stick since you don't have to take it apart.

Both bolt up the same, and require a 2wd NP435 which has the 28 spline output shaft. Both require an aftermarket adapter $200-$400.

Or you can get a 4wd NP435 which comes from the factory with a NP205 transfer which has a 1.99:1 gear ratio.

back when I was choosing T-cases I was told that the J-shift was easier to adapt to go up through our floor, I ended up going with a NP205 behind a C6 and it went right through the old hole in the floor.

I had to cut a huge hole in my floor to get my shifters threw.....

I cut a huge hole in my floor as well, more so for the tranny than the t-case. I was planning on making an access cover, but that hasn't happened yet

My NP 205 is bolted to a C6 that originally had a NP208 on it. So the adapter between the Tranny and Tcase is the short one used with the 208s, moving my 205 forward further than any stock 205 would have sat. That could be why the shifter came right up through the floor and shift boot without cutting anything. The tranny just tooks some tricky linkage mods to hook up the stock B2 shifter to the C6.

I was thinking for running a D-20 (j-type) with a C-4 seeing how I have a c-5 now and maybe a twin stick for it is this a bad setup?

It's a decent setup. No overdrive, but that's not really a big deal unless you do a lot of freeway driving.

The one big problem you're going to have is coming up with the C4 adapter and mainshaft so you can bolt up the dana 20.

The early bronco was the only thing that came with the C4/dana 20. You can get everything aftermarket too.

didn't ford use the C-4 in F 150's (4x4) till 1980

I have read that I can use my C-5 output and it will bolt on the C-4

The trucks used the NP205 transfercase, which has a 1.99 low range.

Gunbunny the point of mating a C4 and C5 is so you can use your stock t-case and driveshafts. If you wanted a Dana 20 T-case you would need to use the C4 output and adapter from a classic bronco that came with a D20.

Wich is a better set up ......I a not set on the D-20 if I can use something else?

I wanted to go with the C-4 becuse I have a C-5 and I understood that it was a simple and cheap way to go becuse I could still use tranny mount and all that good stuff swaping-out with the C-5; I guess I am looking for what would be the easyest setup to start with.

I don't think I want to use my stock T-case it has that push button BS; for all I know it could be the best one ford ever made LOL.

if you are going to use a stock transfer case I would use a manual shift 1350. but if you have a 4x4 c4 with a 205 bolted to it I would run that. you will never destroy a 205. there is a company that has been advertising an aftermarket 205 with lower gearing but I have not seen it priced or for sale yet. I think it was a company called promax. the 205 is known for its dependability but also its 1.9:1 Low range gearing, so you kinda got to pic and choose your battle.

I went with the 205 because that is what I had to work with but I am pretty happy with it. the only thing I get upset with is my shifter likes to stick in 4L so I will have to do something about that before long. also around here there is more mud then there is rocks so I don't need the super low range like others. usualy 4H does fine to keep me on the trail. I did over gear though.

Thanks DBrown

I think that may be the way I look into going

I know that this is kind of hijacking the post but will the 205 bolt-up and fit ok
