While trying to identify my exhaust in another thread I was also doing trans and diffs fluid changes and trans line and pan filter changes.

 

I had got a little underbody panel removal happy and removed panels I didn't need to. While removing the two rear panels on either side of the rear carbon fiber diffuser, I snapped a bolt on one side. And have a seized bolt on the other side.

 

The side that is seized is where the panel is bolted to this bracket that hangs down.  I am twisting the crap out of this bracket trying to get bolt off.  I would like to replace it since twisting it back and forth, I am afraid that I have weakened it.

 

Does anyone know the part number for this bracket that meets the rear corner panel.  It is connected with a 12mm bolt I believe.

 

Also have to replace a couple of 10mm and 12mm bolts, part #'s for these would be much appreciated.

    Thanks for reply Joe.

     

    But the diffuser is fine, I need the two different bolts and the bracket that the diffuser is attached to.

    Always good to remove all the panels once in awhile, especially after winter driving. Small rocks and debris get landed on the top side - so its good to clean that all out.

    Gives you the opportunity to spray rust inhibitor once the all bolts are removed. 

    Don’t forget to clean out the bottom horizontal portions of the wheel liners - they trap all kinds of stuff.

    Yeah there were a lot of little rocks and pebbles up there.

     

    Anyone on that bracket, part number or name?

    These guys have a pretty good online catalog with parts lookup. https://www.nissanpartsdeal.com/

     

    Enter your VIN and then Look under "Body (Side & Rear)" and then "Rear Bumper"

    Might also be a good idea to run a tap or die on the threads to clean things up if you already have the bolts out. Sometimes mine feels crunchy and those contaminated or rusted threads can inadvertently cause crossthreading if you're not paying attention.

    There are sets of SS bolts available for the under body panels. I would purchase a set and remove all of those OEM bolts and replace, they come with the correct size washers as well.

     

    I've replaced all of mine.

    Thanks for the link JohnnyTsi but I can't find it in that section.  I googled all part numbers that said bracket and none of those looks like the bracket I need.

     

    Good idea on running a tapping out the holes especially the two I'm going to drill out.

     

    Slimshady where did you get the SS bolt set for underbody panels?

     

    I will try to post pic of the bracket I am looking for.

    I think the bracket is part of the drafter guard.

    Does the bracket look like any one of the items in the photo? If so Joe might recognise it and be able to help.

    Finally both the 12mm(M8) seized bolt and the 10mm(M6) snapped bolt are out now.

     

    And thanks for the info Joe, you are right with that bracket you circled.  I was thinking it was a much smaller piece and not all together like that.  But for now I think I can reuse the current one for now.

     

    Have to replace a couple bolts though.

    Just curious. From factory, is the entire diffuser under panel made of carbon fiber?
