Size of bolts on back of stock mk1 steering wheel?

  1. My model of MX-5 is: ‘95 NA mk1 Eunos Roadster
  2. I’m based near: Edinburgh
  3. I’m looking for technical help or recommendations on: Stock steering wheel bolts

hey all, picked up my car at the weekend and love it. working to restore the interior to stock and replacing the Nardi Torino wheel installed by the previous owner. I’ve managed to source a stock Eunos wheel however the wheel did not come with the correct bolts to attach the crash pad/horn to the wheel itself. Searching seems to only bring up the size for the steering column bolt to attach the actual wheel itself.

M6x1.0 10mm head.

awesome. thank you!
