I spent weeks trying to find a P60 pill that was made with reverse polarity and then built my own drop-in around it. It was several years ago but I asked on the candle power forums and found a guy who had made a single pill for this and wasn't using it so I bought it from him. I also replaced the plastic lens with glass which wasn't easy either because the lens is pressed in while warm. I cracked three glass lenses before I was able to get one pressed into place. I'm afraid I have no good news for you unfortunately. The only way I found was to get that negatively wired pill and I feel like I was lucky to come across one. Wish I had better news to share and good luck. I love these lights and this one is going to die with me.
EDIT: i wanted to add one thing. Some people say they were able to reverse the batteries in their units and then use a standard P60 drop in. I tried and tried this but it never worked with my light. I have no idea why it seems to work for some and not for others.

Malkoff devices makes several drop ins for the P60-P61 Surefires. I used one in an M951 and it worked great. I picked one with a nice tight beam, color temp can be picked. I used same head in my 6P, and the flood in my G2. Which model do you have? I'm surprised CPF didn't point you to him.
