If you're will to pay for the time to make them, I could do if you really wanted some. They're not too hard to make, it's just the time to do them as it's hard graft scrapeing the holes out as the nearest hole saw I could get was 51mm.

I'd do everything bar the finish req'd, i..e: holes drilled, corners radius'd, brackets to fit.

The gauges themselves on mine aren't held in with any brackets, they're just interference fit so I can just take the centre speaker cover off and push them out if needs be.

Just let me know...
