I've said it many times before never ever look up eBay, Amazon, motor parts stores of after market parts supplier website systems without knowing the genuine Renault part number the Renaultsport cars are never listed correctly and in my experience goes all the way back to the 16v Clio (Williams) things like brake pads, springs and ABS sensors etc., always find the genuine part number and cross reference that with after market parts. TRW make the genuine track rod inners but they don't list it as an aftermarket part my guess is that the manufacturers are not allowed to sell the parts aftermarket if they are the genuine supplier unless the part is used on other cars. I worked for a company in the OEM/R&D dept and helped develop the Tyre pressure monitors (TPM) sensors on Laguna, Clio, Jeep, Chrysler and Dodge Viper in 2001 I road tested sensors in the 2003 Viper prototype in Detroit while launching production fitment to the Jeep Cherokee at JNAP plant two miles from the Viper factory (Connor Road) but anyway we never sold sensors to aftermarket only to the car companies directly and we had to supply spares for 10 years.
