you're right, it is the same. that company also offers the metra one (metra is their usa distributor). it seems to fit a little better, but still not ideal.
if it's not snug, then i'm definitely not going through all the trouble to shape the parts.
in this picture, the bottom layout for the head unit doesn't look so bad, but when i sit in my car i can just tell it won't feel right. then again, with one of the above solutions, the hvac is too low as well. rock-and-a-hard-place.
i will probably cave and get the bottom layout variety, though....
