Were the Dana 20 or 21 T-cases ever available as a divorce mount? Is there any way of bolting on an input shaft housing and yoke from any other T-case that uses a drivehaft (in other words, divorced) input?

I'm trying to figure an easy way to adapt a 2wd ZF 5-spd trans to a Bronco Dana 20. If I can find an input yoke for a D20, I can run it divorced and use a really short driveshaft from the yoke on the ZF to the yoke on the D20.

Yeah, I know there's an adapter for the 4wd version of the ZF, but damn, those things are expensive. 2wd ZF's are about half the price of the 4wd's.

Im not sure about the dana 20... but the dana 21 was available divorce mounted in older ford pickups. I think the 21 is also a single speed case though, no low range.

early mini-truck conversions used a divorced dana 20, they were pass drop but the inputs should be the same? i've got one if you need any parts

I have a divorce adapter for a passenger drop 20. Won't help you with a Bronco 20.

Ford used the divorced Dana 24 (2-spd) in 72-older F250s... and even F100 if you go back far enough ('65-older maybe?)

GM used the mirrored version - the Dana 23 - in some of the late 50's NAPCO conversions. I had a '57 Carryall with one.

The Dana 21 is a single-speed married type that Ford used... 66-75-ish perhaps?

Encouraging news..

Hey, thanks for all the quick replies.

Things are looking brighter - now that I know some of the rice-burners had some divorced D20's, I can search around for one of those.

My plan (if you could call it that ) is to either grab one of those "T100a" cases or a divorced D21 and see if the front input shaft housing will bolt up to a stock Bronco D20 case to give me a driveshaft yoke input for it. I'll mount the Bronco D20 as a divorced case on a fabricated crossmember and have a very short custom shaft made to run from the rear yoke of a 2wd ZF to the D20 input yoke.
