67' and 68' also differ in the plastic lense. One has a more pronounced point plastic lense vs. the other. The other thing to watch for if you are getting into functional factory guages are that the speedo portion of the cluster houses both directional signals vs. dummy lights having one signal in the speedo and one signal in the fuel area.

My 67 came with a 120mph speedminder speedometer.I found a 68 160mph speedminder speedometer and installed it. I like the 160 better. (I used the whole 68 cluster)
I upgraded my 1980 XS1100 85mph speedometer with a 1979 XS1100 160mph speedometer. There is just something about looking at a speedometer with 160mph on it. The government thought that if you put 85mph on it less people will get killed.
That is why I asked, I have oil and brake indicators. I got those pictures from Select Motor Classic Car Restoration Parts. Here is their 67 speedo with speed warning indicator.
The 69' i owned had the speedminder and it also had a low fuel warning with it.

I did not see any listings for Low fuel warnings as an option.
