I'm on IPD's website and it appears there are two types of inner tie rod ends. The website says to check the chassis number plate inside the engine compartment and I did. However, my number does not start with a 4 or a 5. The number starts with a letter "M". The entire code is "M 1 1NAMS5". I have a base model 99 S70 non-turbo 4 speed automatic. Is there a different way I could check if I have a SMI or TRW rack?
