1991 Breadvan headunit choice ?

Hi looking for some advice I currently drive a white 1991 breadie. I am trying to mod it as period as possible so revo rfx wheels, bead seat covers, dtm exhaust etc etc. The prob I have is the stereo. I have a parcel shelf mounted deck speakers a bass tube but hooked up to a modern headunit ?? I found running an old school tape deck just to poor quality so what do I do for it look 90s ?? D onot want to go down putting unit in glovebox so any ideas or what are you guys running ?
