1988 Pontiac Trans Am GTA Digital Dash Bulb Replacement

As the title says, I was wondering if anyone has a step by step picture of how to take apart the digital dash and replace the bulbs behind it. Im terrified of taking it apart and damaging something, everything works as it should (the oil pressure gauge gives me an issue once in a while) I have a few bulbs out as the brake light bulb and the left turn signal bulb so I figured while its all open I just change them all to LED.

Does anyone also know what causes the numeric displays to become all mushed together (odometer sometimes goes to 8888888 and then turns back to normal font). If you guys have any tips or any videos/pictures let me know. I tried to find a video on youtube with no luck.
