Viper hoods have very minimal adjustments.
Unfortunatly for as most used viper owners find out when your hood has big gaps or is sitting weird its because of collision that were never fixed properly.
There really is only one Guy I would take my viper to in LA or anywhere else for that matter. The Shop name is Dianas auto body in Culver City, and his name is Javier(Owner) he is the nicest guy you will ever meet. Sorry dont have the number handy, just call 411.
Just be prepared for news that you will most likely not want to hear if you hood is very missalligned.
