Need to remove ECM out of my 1985 Corvette

I have a 1985 Corvette, I need to remove the ECM to change the Prom out. My Chilton manual says it's in the dash behind the passenger side dash pad. I can't see how that Dash front assembly comes off. I took off the side fuse panel cover and I can see some backets that look like are screwed in from behind that hold in the Dash pad or passenger bumper as it looks. You know it's the section that the A/C Vent is in, the pad protrudes out from the Dash. Can you provde me any help, I really need to remove the ECM. Thanks for any help that you can provide.

- Hi and thanks for writing back, but Corvettes don't have glove boxes. I got the ECM out it's up in the right side dash. Two screws holds it in place then you just slide the ECM down and it will be right there where the floor mat is. There is enough wiring that you don't have to unplug the wire plugs from the ECM you can replace the Prom Chip without taking it out of the car. Once I figured it all out it took about ten minutes to replace the chip abd reinstall the ECM. One thing though..you have to be a contortionist and stand on your head to do this change out. Thanks for responding.
