[Mjpmark]

Hi, can any one tell me what the maximum size speedo instruments will fit into the fatcory supplied binnacle that fits on the dashboard in front of the steering wheel?

Thanks

The standard aperture is 80mm, but if you want I have a spare old binnacle you can have to chop up/experiment on if you want.
