no a stock EB used a 3 speed toploader
to hook a d20 up to anything requires custom shafts due to the goofy way the gear rides on the output shaft
I would try and avoid a d20 because of the sliding gear design, I prefer constant mesh gearboxes

ya an eb has a 3 speed somthin arather with a dana 20. a t18 comes in78 to79 full size. Im building up a bronco 2 with a 5litre and am trying to figure out a tranny and t case combo that will work good. Ilike the t18 because it low first gear of 6.32 and i like the idea of a dana 20 due to its2.43 gear and it is simple and cheap. Im just not sure about linking the two together.

It might be easier to hook up the ford Dana 20 to the NP435 that had a 205 or a 208 behind it, I don't know what Tcases ford used behind the T18, with the NP435 you still end up with a really low first gear, lower than the T18, and if I know my ford stuff right (I don't know the fords that well) the ford dana 20 has a female splined input and a round bolt flange like the NP Tcases and ford mostly uses 1 spline count for the output shafts.

Jeep and International used a T18 and dana 20 combo but the frt drive is on the wrong side for the fords and the Jeep/International Dana 20s are only 2.02:1 low range and they have a drive gear that has to bolt on to the back of the tranny that makes them hard to adapt to anything else.

most 70's ford fullsizes used t-18 borg warners mated to a np205...the t-18 first gear isnt synchonized and has cast iron top cover first gear (6.32:1 1st gear ratio), the np425 has aluminum top cover and also has a low first gear (6.68:1) they came in 64-85 Ford trucks and Broncos and 63-93 dodge trucks

Search the EB sites... there is a trick to it, and I think you start with a 2wd T-18, and then swap out the 3 speed, so depending on what you currently have now for parts should dictate where you start on the swap. Far as I know right now, a D-20 and the 3 speed adapter and a 2wd T-18 should get you in the ballpark.

much easier to run a bw 1356 or 1345 bolt right in and low of 2.69 and 2.74

i am running a 302 t18 bw 1345 pretty much straight swap for my stock bII when the head eventually decides to let go again....
