I am not sure if I am using the fast program correctly but I keep getting 38342 as the seal part number. However there are variations to this number when searching for the part online. These show up as 38342N or 3832M online and they are completely different seals. I have had this issue in the past with nissan fast, where it showed me that GA16 MAF was the same as SR20/ SR16 Part number but when I actually got the part on hand it was completely different to the GA16.
I am assuming it shows you the parent part number on the diagrams but I guess there has to be a way to drill down on the individual part and show the secondary number?
Anyway after searching in many part stores I got fustrated and called Massy motors. After explaining the situation they gave me a PN of 38342-D2100 which they couldn't guarantee was the correct part since they never stocked it before. Judging from the dimensions online it seems to be the correct seal (
