Just to let you guys know if someone has marred up the radio housing and you want a clean look, There is a dash kit from best kits that works really well, its for a fox ford mustang.
bkfmk504 is the part #.
Do you have a picture of it in B-series?
I've got a complete stereo housing for sale, with floor bracket, PM with offer if interested. There are brand-new kits available that go in to accomodate stereos newer than the 2-shaft style, or even double-DIN. Note four small holes drilled on one side (don't know why, some type of mount for garage opener maybe).
That looks great. Nice find.
