I am installing the original tuners back on the guitar. From Low E to high E the numbers go (llll, lll, llll, llll, lll, lll) Now I have different tuners with lll and llll on the back, but they all look the same. They have similar height. Only difference is the top part above the hole for the string is fatter than others. Any help would be appreciated.

I figured it out. The fatter tops are for high E, B, G and the skinny tops are for low E, A, D. They are all the same height, but follow the above sequence of 4 and 3. I wonder what the difference is?
