Upgrading DL3 mirrors to Tow mirrors on Duramax LTZ

[Kidby]

How far does the Trail Ridge mirrors extend? My current mirrors on my 2017 3500 Denali extend just three inches. That gives a total of 104 inches from outside edge of mirror to the opposite outside edge of mirror. I am looking for a set of mirrors that will give me 107 inches total. Trying to adjust mirrors to pull a 102 inch wide trailer leaves only one inch of usable mirror surface on either side.

I know it's a long shot. I've been searching for the last two hours. I need the part numbers for the top and bottom glass for the driver side on a 16 GMC 3500. Had a lady mirror slap me.

No.  Gotta either replace them with GM or pgamboa can do them.  84290982 and 84290965 for the OE harnesses.  Black mirrors are 84228899 and 84284596, chrome are 84284593 and 84691681.  Those mirrors are for diesel engine.

I see multiple mentions of adding these mirrors to 2500’s with the Duramax package.  Will this same kit and part numbers (harnesses and TR mirrors) work if I have the 6.0l gas?  I have a 2018 2500 Denali with factory tiny folding mirrors, and need to upgrade so I can tow the 5th wheel.

So I bought a set of OEM Gm tow mirrors with power everything for the diesel. Your saying I would still need to modify the harness to replace my OEM small style mirrors(power everything)?.
