I have a 1989 4x4 dakota convertible. Before I bought it had the passenger side glass replaced. that was more than ten years ago. The replacement glass has this printed on the lower left side above the door handle.

PPG
SOLEX
HERCULITE
SOLID TEMPERED
SAFETY FLOAT
2 4
AS2 26 0
DOT 18 M27.6


FACTOTY PART NUMBERS ARE FROM 1989 AND MIGHT NOT BE ANY GOOD

Standard 2-door dakota N-body 4352 022-3
Convertible door glass 4549 436-7
Conv.stationary glass 4549 432-3
Rear glass guide 4549 442-3

By the way my user name is ConvX4 I think it is better than the guy I bought the truck from 4XConv. Good luck and PM me If I can help further. Bill
