Transfer case upgrade

[67nukeford]

I have the NP435 and single speed transfer case in my 67 4x4. Is there a 2 speed transfer case I can upgrade to? I was going to go to a 5 speed, but can't find one that will adapt to my 390 without costing a fortune. So, I'll stick with the NP435 (and maybe have it regeared, if possible), but I'd like to get a 2 speed transfer case. Is there one available for the NP435?

Thanks!

I think the Dana 20 out of an early Bronco with an adapter will work.  Do a search in this forum and see what pops up.  It's been done.

You could also get a NP435 with a 205 gear drive out of a '76-'79.
You'll need the tranny because yours is a 2wd with a adapter.
The D20 would be a good choice and it even has a lower ratio, but it might cost more to covert.?

Thanks cep, I think that will be the direction I go. I need to find a donor for the power steering anyway, now if I could just find a truck with a good tranny and transfer case to donate with it!

the bump F250 4X4s  come with 2 speed cases,dana 24s should bolt right in.

Divorced or married?

Definitely skip the Dana 24 (piece of crap) and head straight for the NP205, which is available in either version.

Married. I've heard that about the dana also, so I'll stick with the 250.
