I have a 2005 rx330 and need the two back headrest, found two that are off of a 2003 rx300 and wanted to know if anyone know if they will fit dont want to drive two hrs to get them and not work?

 

I would say that their is a big difference with the seats on 1st gen vs 2nd gen RX.

 

honestly I dont think they will fit.....

 

all headrest across the board will fit, there is an industry standard when it comes the distance of the posts...etc.
The problem is your are looking into 1st gen headrest, they will fit however the color will be off and the actual size of the padding will be different.
