Does any  one have any suggestions or advice as to what I can do to the
floor to  create the "cups" for the seat frame? Or, better yet, anyone have
a URL  explaining how to upgrade a Westy to a jump seat?

How about a large cap screw ( alan head ) that the pin drops into  snugly.
you can bolt right through the floor and put a lock nut and washer with
rubber washers for a seal
