Q. What is the partnumber of the windshield?
A. The Toyota windshield has been discontinued, so only option is an aftermarket windshield.
You can try Carglass, however many people ended up with the AE82 windshield because their system says it is the same. Well: it is not, so be careful with that!
You can also try to convince them to get a Pelkington. The Pelkington part number is: 8249 ABL
