Garbage disposal location
My kitchen sink is 30-70 split. I wash dishes in the large-deep half, but the garbage disposal is on the small-shallow half. This doesn't make sense to me because small food pieces get washed into drain without getting chopped. Strangely my neighbor's setup is exactly same. Is there a reason why the disposal is on the shallow side? If I move the disposal, am I likely to damage rubber gaskets/seals? If yes, are the seals/gaskets proprietary and not available from Home Depot?

You would just need to get under the sink and measure. If the disposal is on the lower sink, you would likely want to go out the side of the disposal with a straight tailpiece that will tee into the drain from the higher sink. Below that tee is where your trap would go. As long as the tailpiece coming out of that trap is going to be a little higher than the rough in at the wall, you're golden.
I would be surprised if it wouldn't work. Only reason it wouldn't is if your sink is unusually deep or if your rough in was plumbed in too high.

Unfortunately, the disposal is attached to the higher sink. I suppose I have to either move the disposal to the lower sink or install a second disposal to the lower sink.

You will need to replace the elbow on the disposal with a straight tailpiece and you will need a new strainer/basket for the left side and a new disposal mounting flange kit (you need the right flange for your disposal) for the right side.
Then you need all the parts I mentioned earlier to hook it up to the rough in that is coming out of the wall.

Sorry I misunderstood your previous post. Yes, the disposal outlet will be high enough for the trap. Both sinks have the same drain opening, 4.5". I should be able to swap out the flanges. If not, Ace Hardware is within a mile. Will report back when complete. Thank you.

Thank you for your help. I should have replaced the elbow from the disposal with a straight pipe (your suggestion) and rotated the Tee by 90 degrees. it would have been prettier than this.

As long as it doesn't leak, looks like it will work. One thing to note, you need to loop the dishwasher line as high as it will go... get a pipe clamp to hold it up high on the back of the cabinet. That prevents the line from siphoning itself dry.
