I stumbled on these clips...
(Note: the new clip is for a Ford Galaxy)

The measurements are a tad large but who knows where they measured it. looks almost identical. I'm buying one and will report back with a comparison to an OEM clip.

 

Place holder

 

Nope there is a seal ( that I'm in the process of reverse engineering) that goes over the fingers and then the outer fingers are squeezed together spreading the inner fingers in the seal and locking it into the body hole.

The leading and I think the trailing clips do get a screw, but they go on the same way with or without the screw.

 

Here is my 3rd attempt at the seal.

I still need to know the hole size in the rocker, anyone... anyone?

 

I agree on the sealing aspect. But the clips don't spread apart enough to lock into the hole. The seal fills the gap and locks it in place. The same type of seal is used on some other trim clips on other cars.

I'm looking for the hole size in the body. My best guess is 5/16" but might be 1/4"

 

0.285" = 9.14/32" ~= 9/32"

What an odd size!
Factory punched hole?

Any chance there is 0.030" of paint / rust on the ID of the hole making it a 5/16" (0.3125)

Well either way I have a better starting point than I had before.

Thanks.

 

Don't know yet but I will post my findings when I receive it.


It looks really promising even if it needs a bit of tweaking

 

I think they would do the trick.


Might need to take the tip off the ends.
