+1 for PB Resource. They have added lamps to my order without me even asking, just to give me the discount. Just make sure you have part numbers and give a good description of the parts so they don't have to spend extra time. I'd be lost without PBR!

I can confirm that the old style base plates are reversible as well. It's like getting free parts in every game! If the original (black anodized) screws are still present, I don't tap the new holes. The screws form the threads. I feel that formed threads are stronger than tapped threads, due to the work hardening of the steel. I use a cordless screwdriver, so the whole process takes just a few minutes.
