I'm looking for anyone that has ever pulled off their rear bumper for their 13-14 mustang GT's. When you pulled it off, did you notice any inscriptions for where the OEM backup sensors would go? I know they are there for the 2012's, but I'm specifically looking for the 13-14's where they changed the rear bumper a bit. I know the bumper typically has inscriptions for the cutting required by valences (Boss 302, California Special, GT500), but I cannot tell from pictures if there are some for the rear parking sensors

I've been looking at installing the OEM backup sensors on a 2014 mustang GT. However, I've run into a problem where no dealer in Canada will upload the AS-BUILT data for a car of a different VIN than the mustang in question, as this bring forth a safety/reliability issue.

So now, I'm looking at installing aftermarket backup sensors. I can have these paint matched and they seem relatively easy to install. I want to get it to look as OEM as possible. I can deal with the wiring myself (seems easy enough), but I just wanted to check if there are guidance marks.

I have searched other threads in this forums to no avail.

Thanks in advance.
