i have a 94 integra, i can do everything to take it out for the most part, i can take out the arm rest, the bottom dash, shift knob and unscrew everything to the point where you just have two little screw in the far back of the head unit, i went to www.integracaraudio.com and they said to use a ratchet with 3/8's bit, but that was too but, and the 1/4 inch bit was too big, and getting a phillips head SD is head at that angle, any one have any suggestions? or any other webpages that tell you hwo to do this?

 

I can't remember what I used with my removal but I would think it would be a metric socket not standard. So check a few socket that are around the same size but mm. If all else fails can you fit a small adjustable wrench back there.

 

I used a Philips head screwdriver on mine...it was a B I T C H to do but I eventually got it. Not to mention you need to conort your body into some pretty uncomfortable positions to do it.
