Hey guys, I need some help. I got a NISMO diff but I didn't get the side flanges that come with it. Would anyone happen to know which part number(s) I need? I have a 2008 base model.

Looking at this thread I think the part numbers are 38220 (specifically 38220-Z33002) and 38220+A (secifically 38220-Z33003) as shown on the courtesy nissan site, but I'm not sure. Thanks for any help.
