'69 RS is on the passenger side - toward the front, also utilzies a different bracket holder for the bottle. Attached pic is the '69 RS application, which is different for non-RS. I don't have the information with me, but as I recall, for non-RS applications in '69, the windshield washer bottle is on the driver's side. If you have a copy of the '69 Assembly Manual, it will show the standard location in the front part of the manual, and the RS location in the back section under RPO Z22.
If you are in need of the correct bracket for the non-RS application, I believe I have one in my pieces and parts.
