Side Mirror Suggestions?

[muddpile]

What does everyone run for side mirrors on their trucks? My 72 came stock with the sport mirrors that are 4" x 6" rectangles, but they are pitted badly and one is cracked, so I need new ones and figure I might as well look at my other options as well as stock. I kind of like the look of the peep mirrors at the top of the door frame, but they look like they are pretty small and hard to see out of. Also, would I have to drill holes to mount them, or do they just clamp on? Also, are there any other nice subtle side view mirrors that would look good on a truck like mine? Thanks!
