I'm looking for the hardware (fasteners and grill) to mount a factory style 6 x 9 speaker in the back of the rear seat for a 71 Cutlass convertible. This is not the same set-up as the mounting locations in the package shelf. Parts can be either new or used, any help would be appreciated, thanks.

 

I have two convertible rear speaker grilles and attaching hardware 20.00 plus shipping. They are new.

 

on my 1971 Conv, with AM/FM & 8 track (all factory), I mounted the speaker on the frame behind the rear seat, as the factory did it for this "stereo" setup (one speaker under the dash and this one behind the seat). Did not really need any hardware other than some screws, since there is space in the frame for it. You use a single wire and the frame "grounds" the speaker.

 

Inline tube sells the original style hardware and grilles

 

This is what you are looking for. I sold this a while back w/ a speaker, probably have another one kicking around here. My 70 GS uses this set up. Be sure you understand how it mounts, it is possible to break your rear window if you use the wrong speaker or mount it from the wrong side, etc.

 

This is a 6" x 9" speaker, mounted on passenger side of the back seat, right?

 

yes, BTW. when the top is done, it is not a very effective set up!
