I don't recommend buying LEDs from eBay for your interior. I had a hell of a time when I did mine. Ended up with several different colors, LEDs that didn't fit, etc. I ended buying the retardly expensive kit from putco and I love them.
PS you're dome is 578 and map lights, courtesy lights are 194. You may have 3 or 1 bulb in your dome depending on ext cab/crew
