Cant find running boards for 06 yukon xl 3/4 ton.

I have. They offer nerf bars but no running boards. I like the nerf bars but the added protection of running boards,here in the rust belt, is what i'm trying to find. Thanks for your help

Thanks Tennisshoes I'm not sure if you're referring to length of bracket or running board. I'm almost certain the length of running boards for all gmt 800 suburban/yukon xl are the same. Most answers from sellers/manufacturers are they don't make a mounting bracket for that model. When i go to search for 3/4 ton suburbans of same yr I see only one more manufacturer but have not called them to make sure. Most web sites that say a certain model will fit, end up not fitting after calling the manufacturer.
