The VX emblem fits perfectly in the black rectangle currently taken up by the Isuzu emblem.

Like VX KAT suggested use a hairdryer to heat the Isuzu badge and carefully remove it with something that will not scratch. Use Goo Gone or T4B's Alky-hol to remove left over adhesive residue.

Once it's clean and dry use the 3M tape supplied with the new VX emblem and center in the black rectangle.
