Speedo cable length for Vixen S1?

[Sonus]

My car is stored so I can not remove the speedo cable, but I need to order a new one to adapt the T5 to my Smiths speedo. Does any know the stock length or have a speedo cable they could measure?

Measured the original one and it was 1600mm. Due to some tight bends and 50mm longer gearbox I am ordering one that is 1750mm.
