Found a 302 , now for transmission/transfercase ..found C6 and EOD .no transfer cases …both should bolt up ..right . But without ECM the EOD won’t shift because it doesn’t use TCM right ? What transfer would work on these transmissions , without an adapter for D20 and still fit without to much modification? Once again thanks for all responses swap gurus.

There’s a lot going on here and I’m sure someone more knowledgeable than me will chime in but, neither a c6 or eod are a bolt in swap for your Bronco. If you’re looking for an automatic and bolt in convenience you want a c4.

Trying to decipher this...

The C6 and E4OD are not good choices for an early Bronco. They are simply HUGE! They don't fit very well.
What can bolt to these transmissions? Ignoring that they are a bad choice, the NP205 is about the only junkyard option that will bolt on without adapters.
The Dana 20, without aftermarket adapters, only has 2 factory options. The C4 and 3-speed manual. The Dana 20 is a unicorn that only works with factory Bronco stuff. Even so you still need the Bronco version of the Dana 20 and not other versions. Or an adapter.

Lets back up and try and find you the right transmission. You have a '66 Bronco. Guessing you are swapping the I6 for a V8?
What are your plans for this Bronco? How will you drive it? What do you want it to do? What size tires? Axle gearing?

And what exactly are you starting with?
In another thread you said "…mine is a 71 frame."
So a 66 with a 71 frame. . . .
What motor mounts are welded on the frame you have, I6, or V8?
Do you have the Ford D20, or do you need a transfer case also?

Yes I have the Dana 20 transfer , I wasn’t wanting to use it ( looking for a newer easier to shift transfer) . Would AOD trans/ transfer combo from F150 fit in there ? My axles are Dana 30 (4:10) 9” rear (4:11) . 32” tires . Looking for overdrive option
