Factory Radio 99 Gt Question

When I bought my car it didnt have the factory radio in it. It has some aftermarket POS and its not even hooked up. I do have the factory CD player in the lower din still sitting there.

I am searching now locally for a factory radio to put in it. I see mine is a Mach 460 from what the label says on the tweeters on the door plus I only have two amps in the back by my rear speakers. Is there a particular radio I should be looking for? I assume not all Ford radios that came in the Mustangs were Mach 460s from 99.

If there are two different radios that came with them what can I look at on the radio to make sure it will work with my Mach 460 system?

Im pretty much just wanting the OEM radio to be honest. I know I might sound nuts but something about the look of it in the car. Besides with a tape deck I can go old school 90's and use a tape cassette adapter as an aux then plug it into my iPhone to stream Apple Music.

I am planning to buy wmburns radio Wednesday so hopefully my search has ended.
