Hi I need a new Knock link and have contacted a dealer for a price and they are telling me that the one on the car (from the chassis and part number) is the wrong one for it

Does anybody know what the differences are between them I think there are 3 different par numbers?

Are they just different connectors or totally different sensors

Thanks

 

Ah ha sorted it the stamping is crap on the case 6's look like 8's
