Thanks WRCProtege, the phots really tells it all. I do, however, want to maintain the air bag capability to the replacement wheel. Am I barking up the wrong tree or what?
The NB wheel swap/retrofit is easy to do. However, there have not been any tests to see if the NB Airbags will fire as required when connected to the NA system. They are different SRS versions, and the NB bags are depowered compared to the NA explosive charge. There are many discussions on this topic in one of the other forums, and to this date, there has yet to be anyone willing to do the test.(poke)
So, Option #1, if airbag is important, stay stock, and have wheel recovered, even repadded a little thicker if that is what you want. Or find a better replacement from one of the Miata chop-shops.
Option #2, If airbag is not important, and ease of swap/stock look is important, then the NB wheel swap would be nice.
Option #3, If airbag and stock look not important, get yourself a smaller, fatter, thicker momo, or sparco, or other high end steering wheel, hub kit, and put your stock wheel on the shelf until you need it again.
Cost:
Option #1 ~$30-150
Option #2 ~$30-150
Option #3 ~$150-300
