First we have to clear up the terminology. Upper Drive line illustration
There is no bearing in the Okie bushing.
There are two brass bushings and a oil seal that are pressed into a sleeve or pipe.
The rear yoke rides on the inside of the front bushing.
The propeller shaft rides on the inside of the rear bushing and the oil seal.
Illustration this is how it should look when the Okie bushing is installed.

The 1953 bushings where press fit into the torque tube, so you don't have drill out any dowel pins.

There is no video that I know of that walks you through the installation.
Check out this 3.55 ring & pinion swap HERE it shows some photos of the Okie bushing being installed.
Also here is GM film strip slides the bushing info starts on slide 22. The slide numbers are on the lower right corner of each slide.

There are two scenario.
1. If there was No Okie bushing sleeve previously installed.
You use a bushing puller to remove the front bushing.
Then you just hammer in the Okie bushing sleeve and your done.

2. If there was a Okie bushing sleeve previously installed.
You might have to remove the torque tube from the rear axle housing.
Remove the propeller shaft and hammer out the old Okie bushing sleeve with a long pipe.
You might be able to get out the Okie bushing sleeve using one of these T-0160-A -Univ- Exten Housing Bushing Remover
without removing the propeller shaft. picture of Remover
