NP 435 Conversion Question

[fmcpeters]

I am wanting to put a NP 435 transmission into my Bronco but a bit confused, I have read where if you use the 2wd version with the square bolt pattern with a T shift Dana 20 and the 6 cylinder tail shaft you do not need any adapters, can anyone please either confirm or dispel this for me. If it can be done and anyone has pictures or good instructions it would be greatly appreciated, thanks for your time.

You still need the bolt-patttern adapter plate between the 435 and the 6-banger t-case adapter housing.

But dear it's just another 300 buck and it'll most likely be the last dollors I'll need to spend on my Bronco ... Keep your fingers crossed when you say this..

About 1/2 way down this page you will see "NP 435 TO DANA 20 ADAPTER PLATE " which is the plate bmc69 is talking about. It goes between the NP435 and the 6-cyl adapter.

Unless you already have a 6cyl adapter sitting around or know where to get one cheap I'd go with a standard 1 piece adapter. it will only cost a few $$ more and its less parts to install.

Thanks for all the info, and clearing that up for me. I don't have a tail shaft so I think at this point if I proceed with the swap it will be a full tail shaft, thanks again!

Cool your jets there turbo! Whatchu mean by "tailshaft"? You should have the 28 spline "output" shaft on your 435 already if its a 2wd version. If you DON'T have a 6 cyl tranny to D-20 "adapter" housing already (or have a line on a REAL cheap one) just get the one piece 435 to Dana-20 adapter (modified 8 cyl adapter housing). There was one posted on here from an Ebay auction not long ago for $150 so they're out there to be had for a reasonable price. I got mine custom made by a machinist in WA who builds them for a song and can PM you his info if you like... He'll build it and SHIP it to you cheaper than you can get that adapter plate using the 6 cyl housing...
