2019-2020 1500 3rd Brake Light and Interior Mirror Needed?

[The Pirate]

Does anyone need a mirror or 3rd brake light assembly?  I just converted my 2020 duramax 3.0 Sierra to the video mirror /camera option.  These are less than 3 months old.  Online the mirror (13595368) goes for about $75 and the 3rd brake assembly (84419006 / 812781034 w/o camera)~$60.  Make me an offer if you need one or both and I'll ship it out to you asap.  All in great shape if you need more pics just let me know, site limits file size.

Can you show us the system you converted to?  Is it the GM system?

Yes, GM parts. 3rd tail lamp with camera $140, coax cable $25, and video mirror $507. Drop the headliner and take off the spoiler to replace the 3rd ~1.5 hrs of work.

Wow that’s amazing!  For some reason I thought that it had to be tied in to the computer.   Can I trouble you for the part numbers?   I want to do this as well.  
 

Sorry to hijack your thread.  Hopefully my replies attract some eyes for you.
