Hello everyone,
Cheers for the help.
The car is on the road and is working fine.
Although I did notice that @ 120mph (er when I accidentally put my foot on the floor) the rev counter was @ 5 1/2.
I've never took any notice of the rev counter when I drove on other occasions, so not sure if this is roughly correct.
Once again thanks to "Tommy20165" who pointed me in the right direction for the part.
Cheers
