Will 116 or 123 Speedo fit 107 Cluster?
 

I need to replace my speedo on my 75 SLC. The local junkyard has plenty of 116 cars but no 107's. I would repair the original but the problem is that when I bought the car, it did not have one. Thanks!

Hello,
If you look closely at the bottom of the speedometer's front face, there will be a part number there, if it is 107 xxx xxx, it is safe to assume that the speedometer will fit a 107. Early 116 cars I have driven did have that speedometer unit with part #107 xxx xxx.
Hope that is of some help.
