I need your assistance in identifying a part number and locating part if available. This is for a 2005 SUT. The plastic piece on the roof that the rear driver side corner marker light mounts to is broken. I cannot find the part number nor a schematic illustrating such. Any advice? Thanks!

 

The part number is GM 15871915. However it's no longer available. I would check eBay or a recycler.

 

thanks!

How did you find this?

​​​​​​Any idea of a recycler?

Is a great resource for diagrams and locating original part numbers. The site is sometimes down so be patient, it usually comes back within a day or so if there is a problem. The advantage is that it shows part numbers for discontinued parts while the GM Part distributor sites remove no longer available part numbers.
