Wow, for us Mopar guys, that is a glaring problem. Nice fix Mike. The wiper you created looks spot on. The "wiper motor" the kits calls for is clearly the "Roadrunner" horn included in the GTX kit. So the black horns you have painted would be correct for your build, but keep that other one for the Roadrunners of the future you will build. Most people don't know that the Roadrunner horn is unique and only used on the Roadrunners. The guys writing up the instructions clearly had no idea what he was looking at.
Nice work, Mike. She really is looking sharp. As a Mopar guy, I approve!!
