Can anyone tell me where the speaker or speakers are located for RPO U80 on a 67 convertible?

The dimples are there, but can be difficult to find. If you use the picture, you can find them.
I'm not sure if you're aware, but the rear speaker magnet depth is important.
Keep in mind that option UPC U80 was one rear speaker on the passenger side, as shown in the AIM.
