Ranger edge drop in bed liner

Good morning All,
I own a 2003 Ranger Edge step side and I 've been searching for a drop in bed liner and cover.
I've been looking for months with no success. It is a small bed about 4' wide by 6' long.
If anyone knows anything that can help I would really appreciate it.
Thank-you, Bud


Sadly as of late I've only seen bed mats, not much selection for the Ranger these days.
