The speaker bolts to the bracket which is attached through the radio control ***** through the dash.

 

But what do the two ears bolt to on the sides?

Yes, Bill, you appear to be correct. I forgot about those tabs. Looks like they're positioned to be attached to two of the bolts that attach the speaker trim to the dash.

 

I'll measure them up and see what I can build.
Thanks

Ok, so I mounted the radio without the speaker bracket. Will have to put the speaker behind the kick panel.
Had to move the Heater cable because of the radio.
Now all I need are the condenser values to eliminate engine interference. Anyone have an idea where to find the info?
Also, if the speaker magnet contacts the metal body, will this create a problem?
If so, if I put an aluminum plate between the magnet and body, would this alleviate the problem?
