What is the best way to get an overdrive auto in a 67 Barracuda?

My painter put a GVOD behind a 727 in a 69 Barracuda Fastback. Minor clearance with a hammer. Said it fits better with a 727 than a 904.
I don't have any personal experience with these guys, maybe someone here has.
727 "SHORTIE" OVERDRIVE TRANSMISSIONS

This is what I am planning to go in our 69 Barracuda Fastback project.
We have a ways to go...

I currently have a 727 with a big block, 355 gear, it's a badass stop light to stop light but just screaming cruising down the road, I want to drive it from Chicago to California down Rt 66 but it will never make it the way it is, unless I drive 40 the whole way. I saw two different versions on the GV website , shorts and longs, I would assume the short would fit better.
