Now's the time to modernize! I put a Double DIN radio in my '98 Z28 with back-up camera, full blue tooth connectivity to my phone, etc. and it makes a world of difference in bringing the F-Body up to current standards. If cost is a concern, you can find used Double DIN Pioneer DVD decks on eBay from a few years ago for $100 these days. Once Apple Car play came out around '14 or '15, the standard Double DIN Pioneer HU's really dropped in price. I have the Pioneer AVH-X2600BT which is NOT a Car Play HU, but still has great blue tooth features with my phone, and lets me have a back up camera ($10 - $15 on eBay) .
Do google search I have no doubt you'll find several pics and posts from where people have put a double din in a TA.
Here's my post over on ls1tech.com from when I did my install:
