[jrd1990zr1]

Both side windows are a total of 27 originality points and 26 condition points. If the glass is correct and just the date code is wrong, it should only be about a 10% deduction (3 points) on originality. 27/2*(1/5). Condition (scratches) are a separate issue.

Check the passenger side glass and see what the date code is for that side of the car. Typically the glass on both sides would be the same or close. I think as long as you are within a few months (before) the build date of the car you will be OK. If you have any problems let me know and I will pull out my judging manual for the 1990 MY to get the codes.

BTW if you drop the spare tire tub, lay on your back and look at the rear bumper sub-frame the production date of the car should be in crayon on the aluminum frame, Quick way to check if you don't have a build sheet handy.
