Thanks Scotty. The trailer hitch was from E-Trailer and specifically designed for the GP which made installation a breeze.
Under the spare is two rubber grommets. You remove them and drop in this plate.
Underneath you raise the hitch up and secure the bolts.
Out back it's the same deal. They use the existing holes in the steel part of the bumper.
After that it's just a matter of tightening down everything down and your all set.
By the way, are you doing Englishtown this weekend? I'll be there either Staurday or Sunday. I'm waiting on a friend to see which day he's going.
