rear headliner trim clips...which direction?

[granitestategn]

I broke my cardinal rule...take lots of pictures during disassembly.

I've got my headliner recovered and the board is reinstalled. I've got most of the trim installed and I got to the rear metal trim piece with my new plastic clips and realized I don't remember which way the clip goes into the trim. The clip has a forked side and a flat side. The clip fits into the metal trim either way. Which end of the clip faces forward in the car? I think the trim might end up crooked if I get it wrong. Does anyone remember which way they go?

TIA

These?

Are the offset differently depending on the orientation? Can you put the lips in the trim and position them without inserting them in the roof to check the position of the metal trim?

Yep. The arrow head goes up through the slot, but the bottom "T" part has two different ends. One end is flat and the other end is forked. It's not visible in the picture because the "fork" end is behind the arrow head. Which end points toward the front of the car?

So the part that clips into the roof isn't centered in the clip..

You could mark the bottom of the strip with tape and a Sharpie, estimating where the anchor points will be based on the clips orientation, and put it up to see if it's right?

The clip fits into the trim piece both ways. There is not a lot of difference but it appears the trim might be tilted slightly if you get it wrong. I can probably figure it out after a bit of trial and error but it would be better to get it right the first time. I'm hoping one of the headliner pros will chime in and make it easy for me. I'm essentially lazy. But not so lazy that I can't waste a day replacing my old headliner. I should be replacing the HG on the old Subaru instead so I can sell it.

It appears centered, but slightly angled.

[SuperSix]

I see.

Well, I think if you examine it closely, you can see what the correct angle should be. I searched high and low using my ninja Google skills, and couldn't find anything on the clip orientation. Someone with a body service manual might be able to get the info.

Yeah, I'm sure I'm not the only one who's scratched his head on this one. Once I figure it out I'll post something about it. Usually I take lot's of pictures when I take something apart. My memory isn't what it used to be. :-)
