You might want to try contacting advance adapters to see if they have an adapter to the 205.

Some of the early '70s 4WD F150s had a Dana 21 transfer case in them. Externally, it's similar to the D20, but it's a single speed unit, so no low range (sometimes referred to as in and out).

It's been said that you could use the intermediary housing that came with the D21 to mate it up to the D20, that the general design was close enough that you only had to drill some new holes around the point.

I haven't actually done it myself, so I can't say for sure if it works. I did do a rough visual insepction of one in the junkyard, and it did look possible, but couldn't say for sure.

If you're planning to use another adapter anyway, then it should work, as it will have the 28 spline output shaft. You'd have to measure the holes across the back of the NP435 to make sure though.
