Part number is P68276500AL and I think this would fit 2019-2021
I do NOT know if this mirror works. Came in a lot of older Dodge Ram truck parts and I could not test it on my older truck. The plastic and the mirror have some scratches and wear but are not broken. Mirrors folds back OK. Has two plugs and the wiring still attached.
Selling for PARTS or REPAIR but you can plug it into your truck and test it if you want.
$40 **If the mirror is still listed then it is still for sale**
