Anything new on any OEM running boards that really fit?? The other half is somewhat vertically challenged so she has a bit of difficulty getting in and out. I'm a bit concerned about some long-term damage to the bottom fascia from inadvertent ingress/egress shoe contact. The aftermarket stuff sorta looks like "aftermarket stuff".
I was going to put on Aries 4" oval bars and was working with the outfit that did "dealer installations" for three local GMC dealerships. As with everybody else, the GM assist steps couldn't be mounted without cutting a slot in the side sill. I was prepared to allow that even though the step would be higher than a correctly mounted bar. An Aries rep came in the shop while my parts were laid out on the floor ready to install. He claimed that they had a fix for the Denali but it would take two weeks to get them from California. That would have meant that they would arrive at Thanksgiving. I'm still waiting for non-existant parts to get here
