hot end hardware?

I'm trying to build a new hot end for my printer but I'm trying to find out all of the hardware. My plan is to build the new one with out having to take apart my printer. So my question is dose anyone have a hardware list for the hot end, has anyone sourced a replacement led strip. I have ordered some of the stuff online, I asked the guys at G create for some help several weeks back and did really get any ware.

thanks for any help
