Diamond Plate Slab (for the rear floorboard area of a Hummer?
Likely...cuz it came from an aftermarket Hummer Upgrader).
Someone is gonna be able to use this. For something.
This Diamond Plate item appears to have been used but its nowhere near "trashed". I grade this item 7.6 out of 10 with 10 being Mint.
This item has imperfections. Surface Scratching and even "knicks and scuffs".
$48
