Hi Mia,
Sure they make it, try this www.sfxaudio.com, they carry a kit for the 90-94 LS400 as well as the wiring harness so you don't have to cut any wires.
The Install kit number is LX3 and the wire harness number is TA02
As for aftermarket brands:
try Alpine, Kenwood, Clarion, Nakamichi, Sony, Eclipse, McIntosh, Pioneer, Blaupunkt to name a few.

Leo,
If I replace the radio in my 1990 Lexus LS400, will I have to do without the sub-woofer? Is there a "classy" looking radio that sort of blends with the interior of the car?
Thanks,
John Boy
