Howdy, Just bought my first car, a black 1984 Celica Supra. It has a few small things that need to be tended to before she can hit the road again. But I'm looking into the interior stuff while I do exterior, I'm trying to keep it as 1984 as it was in 1984. As you can tell in the title this is a stereo question, I'm looking at Sony XR 900 stereo (roughly period correct). I wanted to see if the dimensions were able to fit. 178 x 50 x 150 mm (7 1/8 x 2 x 6 inches) (w/h/d) and 135 mm (5 3/8 inches) (d) in mounting dimensions. Thanks for any help!
