If you wnet with the ford one and a ford Np435 you would not need to purchase an adapter.
(not sure of the input differences between jeep and ford 20's)
use a 435 and either get the adapter from AA to run a jeep dana 20, or use a 203-205 doubler setup, which could be done with a ford 203 (bolts right up to the tailhousing of the 435) and a dodge or GM 205 to get the pass side drop required for the chevy axle...
