Best deal on a 904?

For some reason it wants to start several minutes into the video....just back it up and watch

My 73 340 Duster with a 727 has a Reverse Pattern Manual Valve body that I drive on the street. I use a B&M Pro Stick and I can go from 3rd straight into neutral or 1st gear without stopping anywhere.....really easy,,,

And it is a NO low band apply.....bought it back in 1983 for 69 bucks...lol
