Thanks for all of the kind comments fellas, I took some more pictures today, but I'm having trouble getting them small enough (32,000 bytes per attachment instructions) to get on here. I'll have to read up some more on the camera.
DKasper, no unfortunally they are not Alcoa's, (or 19. 5" for that matter) they are Eagle Alloys. The previous owner had them put on just before I purchased the truck. I know what you mean about the center caps, I've got some rust on the front ones.
