Tract and roller

I have six foot patio sliding door tract and I don't know yet what kind of rollers I have in there. Is the attached pictures will hep you determine the correct tract and rollers for my sliding door? I will also need door handle and screws as all the screws both from up and down are gone. Is the rollers included screws? Also how long does it take to receive the order? Is shipping is free?

I need your help and suggestions.  

Casey, I re-inspect my sliding door and unscrew the stationary glass. The tract on my door is different and it's a whole unit assembly and it's different from the presentation on the video. I will order from you the 6 foot tract and will find out later what kind of rollers installed in there. Thank you, Mr. Poon.
