Someone please school me on the correct speedo for my truck.The po put a 52 speedo in my 1950 cluster and I would like to install the correct one.I've seen two styles used in these trucks,the plain one and the gear shift point one.Whats the one that shows the 3 different gear shift points used for?Was that big truck only?
Thanks
Joe

 

My 50 has the one with shift points and 80mph, it looks like it came with the truck.

 

The F-1 doesn't have shifting points. The larger F-4 and up had them.
