I have a KW with every version of windshield.
Favorite is 2 piece flat glass, followed by 2 piece curved, lastly the 1 piece.
On the one piece when the wiper motor or regulator starts to go out they stop right in the middle of the way drives me crazy trying to get them to park where they belong fiddling with it. I'd rather put in 1/2 of a windshield than a full one at a time, and I haven't had any regulator or motor issues with my older 2 pieces.
Just from looking at them the 2 piece and 1 piece curved glass does look close. Next time I stock up on spares and have a set of each outside of the truck I'll gladly check them out closer an report back, but I bet you get an answer on here quicker than that will happen.
