cuda door glass track questions

[IMNCARN82]

 Not sure if this is in the right section.  But here goes.  I'm getting ready for the glass install and I have a couple quick questions.   Looks like prior to this resto. I had one 70/71 door and one 72/74 door.    Now I have two 70/71 doors on the car.    (the weatherstripping is pop in not screws)   I have one wide track and one narrow.    I think the wide ones are 72/74 (?)      So I need to find a Left side 72/74 track  (?)     Will I have any issues with the 72/74 glass and tracks in the 70/71 doors?         And are the quarter window tracks correct L/R in the pic? 

ThanXxX!!!

The wide one is 1970-71.
Both will fit the doors you have and yes the rears are left and right

I have a set of window tracks from a 74 challenger if you need anything.

Thank you!!   I have 70-72 rollers/guides so I'll look for one of those.   Need a Left side.    Still no word from the glass jokers. Uhg.     So I've been fiddling with stuff.    Probably start with the quarter glass?    Then doors.     Is there a specific order of installation to help ease this process?  Just wondering.  And why are there two positions for the cranks?  Which one should I use?
