1995 ZR1 Winshield

[swamp]

Looked at a September 1994 ZR1 today and could not quite resolve an issue with the windshield date code. The code on this windshield was L L.This would convert for the first L of a March date, however I can not find a reference to the second L. From the stuff that I have the letter should be a N.
Any help would be appreciated.
