Superwoofer, like the stance of your Falcon. If I ever get to working on my 64 it will have the same stance as it compliments the angled side indent.
The "Lido" Falcons don't look right when sitting stock height, but then again neither did "Lido" Iaccoca. No wonder Ford fired him, LOL! (That's a "inside" joke for those of you that know Falcon history.)
Glad you displayed the photo of the muffler, had me puzzled as to why the pipe was coming out from the wrong side of the rear bumper. |
