I was happy with the quality of the Hagan gas door kit, third brake light kit and, the license plate box kit. Can't speak for the hinges.
I noticed someone else that had hinges the other day...Autoloc. I ordered a set of their Bearclaw latches and they threw a catalog in the box. Didn't have prices but, the hinges looked pretty nice.
Found it on their website:
Neat catalog. Didn't have pricing but their website does. Some of the prices are pretty good. The Bearclaw latches where definitely a good price.
