OPP install

[NWD02]

Ok... just got my windows from the group buy and having some issues installing.

I talked to Ben today he said to remove the 2 rollers facing the same direction, which I did. After replacing them with the new ones they do not roll in the C-Roller Channel on page 19. What am I doing wrong??? Does this C-Roller channel bolt to anything or simply connect two rollers?

I think I'm missing a few nuts and bolts from the hardware bag.

In my kit little baggy of hardware I have 4 rollers, only 5 bolts and 5 washers.
No nuts
No round vinyl hole covers.
Looks like I'm missing 4 rollers.
No felt tape.

Anyone who can help make this a little easier any input would be great.

Thanks.
