Many have complained about difficulty in reading the gauges. One solution is to buy aftermarket inserts with custom colors and info displayed. I didn't want to spend a few hundred on my high miles car (130K) so I chose a cheap option. Bring the gauges up from the depths of the dash.
In a nutshell, I put plastic spacers behind the cluster to move it forward, and then cut the "tunnels" to accommodate their new position. The deep tunnels are a styling choice by Pontiac to get that retro look. Cute. Not ideal.
Instructions for removing the boomerang and instrument bezels/tunnels can be found elsewhere on the forum, so I'll skip that. Once removed there are four screws holding the instruments in place and plenty of wiring harness to pull them forward.
Instruments lying loose and still plugged in:
While you're in there, if your gauge cluster is dusty, the plexi cover is easily removed with five snaps... three on top and two on the bottom. The cover is not sealed and dust easily gets in there after the years. I washed mine in the sink and dried it with a soft cloth:
The original mounting screws are #8x1" screws. I got appropriately sized 1" spacers and went with a 1" longer screw (#8x2") from Lowe's:

The bottom, left screw can be a pain to get to. Pulling the air vent to the left of the steering wheel makes it easy. A 7mm socket on a long extension gets the factory screw out. A long, thin Phillips screw driver put the new ones in. Here is the new screw installed (please excuse the New Mexico dust. I live on a dirt road.):

The next step is to cut the tunnels.
