I took a pic of this part. Can't seem to find it on the parts diagrams


but both rubber stoppers are dry rotted. The driver side has no upper part. Looks like it supports or keeps roof from being scratched. Any help would be great!

 

Those rubber "bump stops" are not available to purchase from Infiniti- they rather sell you the whole mechanism for a few grand.

You may want to check this post as someone found a suitable replacement from Home Depot that seems to work well.

 

Awesome , thank you!!
