I used to work on GM AC speedos for a warranty shop in Syracuse from 65-77.
I also did GM Delco radios.
At some point the Speedos had a wick on a brass arm on the last digit to
put a slight purple haze on the roll. Most dried out before it got there, but
put a barely discernable mark on. Other than that , just a good look at
things on the car should show miles. door hinges , window regulators , sill
trim , brakes / backing plates , and lots of other areas.
As far as running the odometer with a drill , do the math , it just is not
worth it. By the time you take enough miles off , the main 2 frame and
magnet bearings will be toast .Please look up info on it to understand why.It
should be taken apart to do the job properly , but gets sticky legal issues
(Federal level) involved , plus most states have a good record of year to
year miles with the inspection logs. The only reason I bring this up is to
save you from big problems (I have seen this , when the state came and
reviewed our logs once).
Only reason I play with odometers now is when I install a different dash
(Spyder in non Spyder etc) , or replace a non working one.
New frames with bearings are getting hard to find , lubing the bearing
correctly is a speacial job. So if you have speedo problems , I suggest finding
a correct dash , and sending it out for repairs to someone set up to do it
correctly. It will save you a lot of grief! (if he is good). No , I am NOT
looking for work!. Now days they are all electronic , so finding a good
shop may take a bit of research.
