Hallo, I have some experiance with such a liner, Its cardboard based, reproduction, it hasnt got the prifiles to allow the air ducts to get to the vents, it basically touches the vents and hangs lower than standard, also the strap that keeps it in place disfigures it at the center, and it doesnt fit snugly around the mouth of the glove box.
reasuming its a cheep temporary solution that you may have to play wit to make fit.
I may propose you this one here
