G60 gear selector

Really need some advice on my mk1 g60 build please!

the car is running a 02a g60 cable gearbox but I'm missing the gear selector, I've had numerous parts delivered but none fit.

has anyone got any ideas of either sourcing the right part, what the right part is or any other way I can get this gearbox working.

other than that is there any specialists who can get this resolved?

thanks in advance.

regards

steve
