Yup Its An 88... I Knew It Was Simple But I Figured It Would Be Better To Sacrifice A Little Pride Then Spend A Couple Hours Pulling Panels Off By Process Of Elimination.
Thanks Man.

Hey, while you have your glove box door off -- Can you snap me a picture or two of how the ECM is mounted?
I want to move my TPI ECM over to the glove box side of things, and would be interested in seeing how the general installed the ECM from the factory

Do I dare ask why you are pulling it? 
Don't know as I have pictures, GM just uses a piece of beige or white plastic mounted to the underside of the cowl, one metal strap holding the ECM into the plastic piece.
Most of the trucks '81+ have the metal mounting tabs in place already from what I've seen. All the 305's that vintage had ESC IIRC so they needed a mount, but the plastic piece is different. Mounting is the same. Any '81+ CCC truck or '87+ TBI will have the plastic piece you need. The ESC trucks are a crapshoot though for stock mounting points, I believe up to some point the ESC computer was mounted over near the gas pedal.
The tabs are triangular shaped and tack welded to the body. PITA to add I'd think.
