WS6GTA

I have a 88 Trans-Am GTA with the factory digital dash. I No longer have the wire harness that sends it all the signals so it is basically a useless corpse. I was thinking of replacing the digital area with aftermarket analog/or digital gauges (round). But the openings are square and small. Has anyone removed the entire digital cluster area and fabricated a facia to hold gauges??? If so any pics would be much appreciated. IF i cant find a way to power my system back up i will need a backup plan to see how fast im going
