I don't believe USDM plate deletes will work. The Spacing on the bumper does not line up with the plates so im assuming it wont line up with the delete.
On mine im running the plate using Bolts, nuts, and washers.
If youre going to delete the plate just have a body shop smooth it over. Looks much better that way.
Where did you get your fenders from?
These seem expensive for knockoffs.
