I have a rear passenger window from a 1995 Lexus Ls400 I really need a rear window for a 1990 model figured out to late they weren't enterchangable if anyone has one they'd like to trade for my window or just has a spare I'd really appreciate the help

 

Rule of thumb, body parts from Generation 1 will not work on Generation 2 or the other way around.

Generation 1 is 1989 to 1994. Gen 2 Starts at 95 and I thought 97 ended it, and then gen 3's but I guess that isn't correct, I don't know what is with those years.

 

95-00 are the same chassis (2nd generation), but there are differences between the 95-97 and 98-00, inclulding the glass.

OP will need a 1st gen (89-94) rear window.
