I began this thread looking for the name and part number of the gutters that run from the base of the windshield over the doors to the C-pillar. I found the part numbers (Thank's to 01_Excursion) but now have a question, how are they fastened in place, are they glued?

4C7Z-7851223-AA (L.H.)
4C7Z-7851222-AA (R.H.)

 

Doesn’t anyone know how they attach, are they glued?

 

Not wanting to see you twisting in the wind, can you show a photo of the part you are talking about?

If the part you are replacing is the dual purpose rubber weather strip that also serves as a hidden rain gutter beneath the clam shell doors, then that just presses into place.

If you are talking about outboard groove on the roof above the door where the roof skin is welded to the body side structure, that groove is filled with body sealant and painted.

You won't need to do anything if you stop making rain!

 

It appears to attach, maybe glue (Super Weatherstrip Adhesive is what I would use), to a sheet metal flange. See below.

I also pulled in the part number you listed and it in fact does slide or snap onto that flange. Seems to have the metal insert to grip the flange. I usually pinch those tighter than delivered to get max bite prior to install.

 

"If the part you are replacing is the dual purpose rubber weather strip that also serves as a hidden rain gutter beneath the clam shell doors, then that just presses into place."
Yes I believe you are correct. It's attached to the body (not the door). That is why I refer to them as rain gutters. When I wash the truck I take a rag, peel it back just enough to get a finger and rag in there to wipe out the years old black grunge. I'd like to replace mine.

 

**UPDATE**

I found both part numbers at the same dealer and can't believe it. They even verified that both weatherstrips are there so of course I layed down the plastic! lol

If anyone is searching for these, I suggest calling different Ford dealers and cross your fingers. Bodyparts, interior trim, and other Excursion parts are becoming rare!!!

 

They just press fit onto the pinch weld flange as mentioned above. The new OE gaskets will have a drain hole in them to drain the water from it's own gutter system, I found mine were closed with rubber mold flash, you'll need to inspect and trim as needed so they drain.

 

Thank you for the tip. Does the pinch weld continue along the A-pillar?

 

Beautiful CAD picture! It's nice to see a cross section for clarity. Thank you!

 

Look at yours, but yup... Tucks under the windshield trim, and the foam wedge by the fender.
Pics from my parts X. The newer stripping was improved over the old one as I remember. The drain to examine is at the rear end that's over the read door.

 

Exactly what I needed before getting into trouble. lol
The new ones just arrived today. They’ll probably get installed during the week between the holidays along with the new air box, upper radiator air deflector, and a couple other minor things. It’ll feel like Santa finally arrived!
