Hi Rodney. I'm one of the older ones, but I don't bite, I gore people.
I would go with putting the lexan base on the router table, centring it very carefully, and not being afraid to drill the holes and then countersink them.
If you miss, you can always rotate the base and try again. Also, first make a template of the table holes on a piece of clear acetate, and see if there are holes in the router bottom that will fit the holes in the table.
Lining up holes with a base or table is a bit of a PITA, as I reminded myself today as I attached the base for a pattern-following thingy. Good luck, I'm sure you will solve the problem satisfactorily.
I have a Ryobi table and Mastercraft router (Canadian Tire house brand, probably chinese and maybe the same as Ryobi) which work marvellously together.
I'm not slow, I'm pacing myself!
