If you look very close in this picture you can see where the spring goes against the roller. Locates on the far left top.
Here is link to more pictures http://s193.photobucket.com/albums/z238/1badss396/Window Guide Roller/
Also I am pretty sure all the other window stops you have in your picture are for the front doors and not used in the rear quarter windows.
And just so you know my car is a convertible so my rear quarter window guides I think are shaped different than a coupe car.
All those parts do go to your 69 windows just so you know.:yes:
The 2 springs are for your rear quarter windows.
And the other 2 post like are windows stops.
And the 2 other ones are also a window adjustment stops.
