I have pretty much done everything to my Escalade EXT you can imagine including installing a gullwing door kit! These were just about as hard to install! I wanted to keep that OEM look, but with a wow factor. This definitely does that. They were a little hard to install, because of the curve on the corner and that bump out on the side. Cutting out the reverse lights was easy and did not damage my factory light. Highly recommended for DIY type people or to have professionally installed.
