NP435 Swap

[old yellow stud]

Hi everyone, I am finally back from being overseas. And now have to start on my tranny swap from the 303 to the NP435. I pulled the 435 from the donner bronco before I left. I pulled my tranny and transfercase Monday night. The only thing I have left is pulling the bellhouseing and replacing the clutch. I don't know how old the clutch is so thought I should do that while I was already in there.

This is my first time doing such a big project and I am really nervous about screwing it up. Is there any last minute advice anyone can give me on this? Anything to watch out for? I already have the tranny's slpit from thier respective transfercases. I am using my transfercase with the 435. I can't use the one that was bolted to the 435. It has something wrong with it and am not sure what. Plus it is a twin stick and I don't think I need that.

I am pretty sure I have everything to finish the job. Just very unsure how to do all this. Oh yea another quick question before I forget. I already pulled off the clutch spring to get ready for the bellhouseing to come off. I how do I get the spring and everything back on. I pulled it away from where it was hooked onto the frame and it all just feel apart. And I can't really see how it all goes back together.

Thanks for you're time

check this site out

they have some info on it.

I'm going to be doing the same sometime in the future

you will need an adapter if you use a dana 20 transfercase and if you use a np205 you will have to fabricate mounts for it (its alot heavier)

tell me how it goes when you get done

This is a corrected write up I did a few years ago on swapping in the NP. This is one of the simplest swaps for a tranny out there for EBs. If you have questions, I will try to answer any I can.

The T-case that was connected to the NP435 was probably a NP205 which is almost bullet proof. Twin sticks are the way to do so you can have 2wd low or front wheel drive only. But I can see a rebuild can be costly.
