Window glass - codes

[Tim Cressy]

Evening All,

My 2010 Focus Estate Titanium has clear windows at the front & privacy glass from the rear passenger doors back. I'm wanting to change the rear passenger door glass to non-privacy glass, as when road-tripping with friends, they complain that it's dark in the back & the scenery can't be appreciated the same. However I'm confused as to which glass I should be buying! My car currently has the following codes printed in the glass:

• 43R-002687 = front windscreen
• 43R-000016 = both front door glass
• 43R-001108 = all privacy glass (rear doors, windows & boot)

Do I need to get rear door glass that is 43R-000016 to match the front doors, or can I use 43R-001057 (a lot of which is for sale!) without it looking noticeably different/odd?

Any info on the codes or guidance would be appreciated - many thanks!
