Gear box brand?/bushing

I have a mid 80's John Deere 522 with a gear box that I don't think is original(maybe Ariens?). I need help identifying it. Also the bronze bushings are not typical in that they are keyed to fit into a grove in the gear box.
The main issue is that the key in the keyway broke on the 3/4 shaft making the shaft not turn. While taking it apart I see that the bronze bushings are worn down too. The worm gear looks good. So, I need to replace the key and bushings. Do I have to use the keyed type bushings or can I just use the ordinary non-keyed ones? I can't seem to find the keyed type of bushings. They must be obsolete?
Any help would be much appreciated!
Arrgh! I guess I can't post pics since I don't have enough posts.

Yes.
I did see those Gilson ones. I think my flange where the keys are might be a little wider. Do you know if they are 3/4"?
Do you think I have to have the keys to keep them stay put in the gear box or can I use the non-keyed ones?
I wish I could show you some pics!

5/8" ID
34/" OD
1" Flange Diameter
The flange has a flat opposite the key

The key mainly keeps the bushing from spinning in the housing. If you otherwise have a substitute that fits use some Loctite bearing mount compound to lock it in place.

This design also allows the bearing to be somewhat self aligning so make sure it's in a happy place before the Loctite sets.

This one has a 3/4 ID, 1" OD, 1 3/8" Flange diameter, and keyed on both sides of the flange. No chance of finding something like this?
