Really nice, Fred. Perfect. Oh...and some old info from the Seal gray thread, which I posted there:
Yup, they hang on that rail...and are additionally glued to them, bullet proof.
takes a strong arm and a (professional) power-tool to drill those screw-bolts into the metal

Drilling holes beforehand is not recommended due to corrosion issues.
Take your time!!
...if you slip off while drilling, pushing with full power --> free dents and scratch marks
