When I was in the junkyard yesterday I came across a '68 F600. The F600's in those years use the same cab as the regular '67-'72 pickups, but they have a different, much nicer gauge cluster which is sought after since it is a bolt in swap in the regular pickups. Well I found one yesterday and got it for 20 bucks. I plan to put it in my '71 F250, so I took it apart to clean it up and repaint it. I noticed when taking it apart, that the back of the speedometer looks alot like a Maverick speedometer. Sure enough, it is a direct bolt in swap into the Maverick gauge cluster. The difference being the speedometer cable screws on instead of clips on. This could be solved by using a '67-'72 Ford pickup speedometer cable. Got to looking around and have this old VW speedometer laying around. Sure enough, once again, it fit right in the Maverick cluster. Just thought I would share my findings. When I go to NC next time, I'm going to get the gauge cluster out of my grandpa's '63 F700 school bus and dissect it. If I remember right, it has a silver center in it like the Maverick gauges but different numbers and stuff. I also am going to look at the '59 F100 sitting up there.
