Anyone install a Deezee bumper step? Their website says #DZ6204S fits 2015-21 F150 but the one they sent me won't mount on the studs on my '21 XLT, the mounting holes are too small. Even if it did fit on the studs, it appears to me that the extender shaft on the step wouldn't clear the lip on the flange where the step mounts. I suppose it's possible they sent the wrong part#, it's not stamped on the part. Disappointing because it's otherwise exactly what I was looking for, don't want a folder. Thanks.
