I have a 1971 that has spent it's entire life in Arizona, in the heat. So the grease on the odometer hardened up a long time ago and the white wheel with the 1/10's of miles broke into many pices.
I bought another early cluster speedo on eBay from Idaho, not so hot, and removed the odometer from that unit. It was stuck but not broken. Dis-assembled it, cleaned it all up and put it back together. I installed it in the original speedo, not the eBay one. That eBay speed had a red wire soldered to it that was cut, my irginal 71 did not have a red wire.
The odometer works but all of the barrels roll over on the 5 not the 0. So I got to 20 miles and it went back to 10 and then rolled over to 25 when the 5 came around again. All positions roll on the 5.
