I put a glass front clip on my 65 C-10 with glass inner fenders. Since it was wrecked I decided to go with glass because it was cheaper and lighter. I've only had it back on the road for a couple months, and I already have a "star" in the glass on the front corner. I thought that the inner fenders would protect it a little more, but ... I guess not ... If you decide to go with glass I definately recomend applying the bedliner coat for added protection.
