I know they will probably fit but do they both have lock cylinder holes?

 

[03rado]

they will work, don't really know about the lock cylinders holes. they should have them

 

[HumanZoom]

Yeah...2003 will still have both holes for the locks (99% sure). I know my 03 Sierra does, but when I went to the dealer to look at the 04 Sierras, they only have them on the driver side only.

 

[BuiltNotBought99]

yea I'm like 99% sure they are the same on the 03.

 

[03rado]

they are the same but some handles only have one key hole for the drivers side and not one on the passenger side, depending on what part # you get
