They are one and the same in the rear as in the front.
The front ones are tight and secure when bottomed, not so in the rear.
The center clip would be ??? Clips, Moulding
or as the type at the link, you posted?
I' m undecided about the rear, it sounds like a clip on the underside, so it may not be a great idea to try drilling and tapping, thoughts?
Thanks
