Rear Speaker/Defrost Blower Housing

[dgraver]

Finally getting to the stereo system in my car. 72 rr GTX with factory rear defrost. I'm keeping the original look by leaving AM radio in the dash and installing a hideaway system. Front 4x10 is no problem, however, the rear is the issue. Whatever speakers there were have long since been removed. There was a thread somewhere discussing this topic, but not much detail. I'd like to install either 2 6x9s or 2 5x7s under the rear package tray. Right now the defrost blower is mounted in the passenger side speaker area. I have found blower & speaker housings for 70-74 E-bodies allowing you to mount the blower motor and speaker side by side, but nothing for B-bodies. I'm not sure if this housing would work for my car. Has anyone solved this issue? If so, how? Any input would be greatly appreciated!

I just checked my '74 and I have the vent but my blower was gone. So I then checked my '72 A body and the vent is the same as the B body. On the A my blower mounts down low in the center between the 2 speakers. It is well out of the way of the speakers. I would expect the mounting to be similar on the B body.

A pic of yours would be nice, then I can visualize better what you have there.
