Thanks Rob, that's what I figured.

Yeah, I just checked the parts online and came up with the seperate #'s.

Now I guess the remaining question is, as crappy tire did the install of the master cylinder and the vin # is equal to the base model... would an incorrect master cylinder bolt on? I told them to get the turbo and the part # is not listed on their invoice actually... I'll check tomorrow.

And also, if the master was bad, would it not be noticeable / effect the hydraulic system working properly?
