oooh .. i think he had his dashboard cut! i was thinking of placing a stereo in my 120y(b210) too.. but..i found the hole on the dash is a kinda too small, maybe i'll just place it on the top, at the "silver colored" area!
This pic wasn't exactly taken for the purpose of seeing the radio, but it does show the location of where I mounted my mates radio in his old 120y wags. A new plastic piece was made to cover the holes left from the D badge and the little pocket. It was then cut out for the radio. The original radio location had a factory blanking plate. (not shown)
