Yes, there is one more on top. You'll need a 7mm socket, ¼" ratchet, and about 10" of extension. Once that's out, you're home free. If you remove the larger (8mm) hex bolt from the lower right corner of the dash, you can flex the dash panel outward slightly to make a little more room for the ratchet and your hand. If that doesn't work for you, removing the upper dash pad and cover allows easier access to teh last screw. Removing the dash pad is not very difficult either - Just a handful of screws, the most difficult of which are in the defroster outlets.

hehe...I just did mine today and posted tips on how to do it:

https://www.thirdgen.org/techbb2/sho...hreadid=333174

I removed the dash pad and a bunch of little screws, probably 7mm. I also removed the two 10mm bolts holding the dash to the right side of the firewall and also removed the ECM carrier. It's held in by 2 screws down at the bottom of the dash. After doing this, it's pretty easy. If you've never done this before, I urge you to check out the thread linked above because it may help save some time & aggrevation.

Ok guys well its in and on reassemble I cant get that top screw back in. It feels pretty tight with only 3 screws in it. You think I will be fine without that last screw?

It may be fine. Without that extra screw, it may also begin to sag and create a gap over time, especially when exposed to heat. To me, it's worth a little extra effort to install all the fasteners.
