Ultima Overdrive Gear Question

[Woober Goober]

Hey gang,

Anybody ever mess around with putting overdrive gears on an Ultima. I got a nice handful of them off ebay for practically nothing, and was going to install them. I was trying to figure out how the heck to make this work. If you look at the picture, you can see the whole through the gear is huge!!! Much bigger than the shaft that normally holds this gear; so, does that mean you have to get a couple flanged bearings to put on eiher side of the gear hole? Any help would be greatly appreciated.
