UPDATE:

Solar Guard Tint- 20% Front, 35% Rear (over Privacy Glass)

Note: FYI 35% Solar Guard Tint over the factory privacy glass matches perfectly with the 20% in the front.

There was not a straight answer for this when I searched the topic.

Sorry for the photo quality! I will re-snap some in better light later.
