Don- Got the radio mounted (left of steering column), made a brace similar to your original.
Justin talked me into a 6"x9" speaker and I'm very happy with it, puts out very good sound. Only issue was finding a place to mount this larger than stock speaker. I've decided to park this speaker on top of the original brace that runs from dash to firewall, will be up out of the way. I can send some pics if you want.
I guess I'd better get the lead out and hook up with a posting service.
Later
Jim
