MR2 Aw11 door glass, are 1A and 1B the same?

Hi Guys,
I need to replace my drivers door due to a recent friendship with a truck. Not many are around but I have found a 1A early level door glass and a 1B door shell.
 
Has anyone had issues mixing and matching early glass into the later door shell? I know the door cards are incompatible, maybe the motor mounts as well.
 
Regards,
SteveB
