window guide "U" bracket directions

[bobh67 18]

I know that this has been discussed before. But A buddy and I are at differences on this. On a 69 mustang (has bolt in door glass) which direction are the two channel horseshoe shaped "U" guides face. Do both have the openings face the rear of the car or do the openings face each other?And are both the LH and RH facing the same?

Pretty sure the openings face the rear. See below (gotta zoom in, and still tough to tell)

 

 

 

Pic from Mustang Monthly on a 70 bolt in conversion, and they have theirs facing the rear:

The opening is to the rear of the car.

You can’t actually install them the wrong way as there’s a cylindrical extrusion on the piece that’s glued to the glass and a corresponding indent (hole) on the c-clips.

The c-clips are the same for both right and left hand side, note though that the bent channels that they glide on are not. They are marked at the base with LH and RH.
