MGC / MGC GT / Austin Healey 3000 4" Tachometer and Speedometer

I have a matching pair of  6 cyl. 4" Tachometer and Speedometer. They have been completely professionally refurbished and include new chrome bezels, new gaskets, thumb nuts etc  I feel that they present as new. The odometer has been zeroed.  I purchased them from England to put into an MGC conversion not being able to secure 4'' gauges anywhere. If there is a difference then I think that it will take a very educated eye to pick it. The speedo is cable driven while the tacho is electric. The tacho is presently negative earth set by the vendor at my request for the MGC but I believe it is easily re-set back to positive if needed.

I think these would certainly suit a left hand drive to British dash conversion for anyone doing an MGC and will also likely suit a BJ8(?) Healey
