All,

I' recently joined the forum but have been creeping on this site for a long time. I have read many NP435 threads and still I'am un sure if it will work. I ended up buying a NP435 and 205 for my 1975 Bronco, seller indicated it was from a bronco and it should work. The PROBLEM though is its a 31 spline output. Can this be done? I know I should have kept looking for the 28 spline but that is my mistake. I know I will have to build a cross member and a longer drive shaft (already planned on it since my lift kit is in the garage). Any tips from the pro's would be greatly appreciated, or if it wont work and someone has tried please let me know. Thanks for your time and knowledge!

Hey there. Welcome to CB as (as a member) finally!

Are you planning to use the 205, or were you hoping to keep the Bronco Dana 20?

Welcome
It will work if you keep it as a set. you cant use the NP435 with the D20 unless you change the output shaft. If you want to keep the D20 then you need to look for a 2wd Np435. Then you wont need any crossmember or driveshaft mods. If you use as is you've already figured out driveshaft and crossmember mods will be needed. You may also need a different rear yoke for the tcase unless you got lucky with the setup you have.
