Default transmissions?

I was wondering if it was possible to switch a 4+3 to an automatic on a 87? if so how hard is it to do, and do i have to fabricate anything?

The '87's had the 700r4. The most difficult part I would think would be to figure out how to lockup the torque converter on a 700r4. Somebody must know how to do it around here. And what about the TV cable? Does the 4+3 have one already? I don't think they do but maybe I'm wrong.
