2019 Silverado HD 2019, Black Crew Cab, 6 Speed.
I have a set of Rokblokz mud flaps for sale that will fit a 2015 and up colorado. They don’t require any drilling. I paid $129.00 for them and will sell them for $80.00. We sold the truck before I put the mud flaps on. They are black and it is a set of four with all of the mounting hardware and instructions. They are brand new. I will ship if you pay for the shipping.
