To use a D20, the 435 has to be from a 2wd. The adapter from a 170 or 200 six can be modified for this swap.

The duallys may have 31 spline output. I have been told this but have not seen it. You need 28 spline to mate to dana 20. $100 is decent if you know it doesn't need to be rebuilt.

Ok you need a NP435 with a 28 spline output shaft. These can be found in almost all of the 2 wheel drive ford trucks from 69 to 83. They are also in the four wheel drive trucks witht he single speed dana 21 transfer case. the 435 is easy to identify from a t18 or t19 because it has an aluminum top cover. Then you need an adapter. There is no stock adapter that will work there are basically three choices. buy a new cast adapter made by advance, buy an adapter made by cutting up and welding a plate to the Bronco V8 tailshaft housing, or buy an adapter plate that goes between the Bronco 6 cylinder tailshaft housing and the NP435 from Bob sanders, and then find a Bronco 6 cyl tailshaft housing. Actually since you have a swapped in 455 you might have the 6 cylinder housing in there already The V8 part is 9 inches long the 6 cylinder part is 2 or 3 inches shorter than that. All these adapter options come out the same length and they are all the same length as the stock 3spd dana 20 with the V8 adapter. They all work fine. If you have the 6 cylinder adapter already that would be the cheapest option for you since the adapter plate that goes with it is only $100. Chances are you have the v8 adapter though in that case the cheap route is the welded adapter which runs about $300.
