Sears table was made to fit that router. Just how many different models would fit the same table I'm not sure but it could have been quite a few. I had one years ago that was stamped steel and had a 3 bolt pattern. You took the black plastic sub base off and the countersunk holes lined up with the ones on the router and the top was thin enough that the same bolts worked to hold it to the table. It wasn't much of a table, it had a small top and had to be on a level surface as it would flex easily. That router and any Sears routers that start with a 315. were made by Ryobi so the Ryobi table might work for it. Make sure it has the same bolt pattern. Any other table will need an insert plate that you will probably have to drill yourself to fit that router. There is a thread on the forum for doing that and you can get help by starting your own thread.
You should start considering upgrading to a newer router. There are pretty much no parts left to fix that one with should anything happen to it. CPO outlets sell refurbished routers at a considerable discount and they come with a warranty.
