The plate after some trimming.



The plate with the TBI unit attached.



Side view. You can see just the edge of the plate but I didn't want to remove any more of the plate because it's some aluminium flat stock I had handy. It's about 1/8" thick and I am concerned with warpage. A little thicker and I would have formed it right to the edge of the TBI. It's not a critical area since the IAC is actually a "designed" vacuum leak but I figured, "better safe than sorry".
