I moved from Michigan to California and in Michigan it isn't required to have a front license plate. So after I registered my car at the DMV and received my front license plate, I quickly realized I had no way to mount it. I went to the local Honda dealer and bought the bracket, bolts and screws I needed but how do I put this on? There's no way to put my hand inside the front grill to hold the nut while I bolt in the bracket. Is there a special tool I can buy that can hold the nut in place while I put the bolt in?
How do they do it at the dealerships?

Thanks!
Dan

See if there are not little "nubs" protruding from the front bumper, where you can mount the plate. The nuts are often behind the nub--just use a nut driver to attach the plate with 10mm bolts.
