Need help with side window weatherstrip (71-74 charger)

[nge]

I bought new Metro glass weatherstrip (the ones that press into the "channels" above the doors). Metro does not label the right or the left strips.
My old weatherstip was too far gone to use as a guide.
I havent used any glue yet, so Ive test fit them both ways and the door closed each way...
BUT I cant for the life of me determine which on is the passenger side and which one is the drive side. 
Any help would be appriciated!
Thanks!!

This is the best picture I have, Other members may have better. From memory there is a ridge that fits up against the inside lip at the top of the channel.. When installed the bottom of the weatherstrip will curve inwards so that when the glass is up it will seal up against it. Hope this helps.

Wow thanks for the quick response  .
Based on your expalnation if the ridge, I think i have it installed correctly.
thanks again!!

don't need to label... the finished end cap will tell you which ones goes where

I see some writing in the end caps but nothing obvious, like L or R.
What am I looking for?

just how they accomodate on to the panel . Molded piece meets the body

No need to complicate this! You are correct the end cap does not say right or left, follow the ridges. The bottom will curl in towards the car if you have it installed correctly. You can see what I mean in the photo.
