NP435 install

[Damnitboy1]

Has anyone installed an NP435 in there EB using the existing transfer case? I want to know if it will fit? It is out of a 1986 F-150 4x4. My Dana 20 is messed up and I don't have the funds to build I right now, just looking to get it back on the road. Thanks

What transfer case came with the 435? If it's a NP205 it will fit with a custom cross member. You will also need a shorter rear driveshaft.

Odds are it's either an NP208 or more likely, Borg Warner 1345 transfer case, and as such not a good candidate for an EB due to the narrow frame spacing. The NP205 can and does work well if you don't mind the pitiful 1.96:1 low range.

yeah I think its gonna be an NP208, So I guess saving for the 205 or the dana 20 rebuild is my option. Just curious can I use the NP435 4x4 trans with the DANA 20 or does it have to be a 2wd?

You can use the 4wd np435, but have to swap the 31 spline output for a 28 spline output - and cut it to proper length. And you will need to np435 to d20 adapter, or make one.

Like this, if you have square pattern: https://www.tomsbroncoparts.com/product/np435-adapter-kit-125-refundable-core

Also, double check to make sure you don't have the T-18 common in those year Fords. Also a great trans with granny low but is about an inch longer. Still adaptable, just different.
