Door window weatherstrip question

My 813A1 window was cracked so bought a replacement window and decided to change the window weatherstrip at the sametime. I followed the TM - popped the 5 clips into the holes in the door with the weather seal (which is shaped kind of like a capital L). I assumed the "L" shaped item goes upside down with the rubberized side facing up or the base of the "L" rubbing against the window to keep water out of the door. Looks simple just lower the window in and it will bend the rubber down a bit but then the first time you crank up the window it should bend right up.

My problem is that when lowering the window into the door the window frame hits the weatherstip and as I push down on the window the weatherstip clips start to pull out of the door. It's like there isn't enough room to slid past the weatherstip. I already damaged one weatherstrip. Am I doing something wrong? It looks so simple. Thanks

I installed the "L" strip upside down with the leg of the "L" pointed toward the cab.

I mounted it the same way, but just cant get the window past the weather strip.
