Boss kit / hub adapter for NB?

Hi,

Does anyone know of a boss kit to suit the spline on the NB? It's for an OMP wheel which I think has 6 bolts with 70mm spacing between opposite holes.

There's plenty around that say they will fit the NA up to '97, but I have no idea if the NA and NB share the same spline.

I've attached a pic of the spline measurement but I'm not even sure if this is the correct way to measure it! :oops:

According to Miata.net Garage Compatibility it seems there are fitment problems - see last entry under aftermarket: http://www.miata.net/garage/compatibility.html

Just for people doing a search later on; the spline is the same so the boss kit will work, but you may need to crack out the Dremel to make some allowances for the clockspring.
