Odometer roll back

Unless your state title says "Exempt" in the mileage box, don't do it until you get written permission from DMV to do it. It is technically a violation of Federal law to alter mileage on a motor vehicle unless the title is marked " "Exempt" or "True mileage unknown" by DMV. If it is allowed in your state, it can be done with a dental pick, or disassembled and re-assembled. If it is close to 100,000 miles you can put the speedo cable in a drill and slowly spin it past one hundred to zero. Best way is to send it to someone like Classic Instruments and pay for it to be professionally refurbished.

Thanks, the '65's are metal also and I've tried but still can't seem to get it done, like working with a Rubic's Cube! Cylinders keep catching on the metal rings with the tabs on them and can't separate the cylinders from the metal tabs/rings enough to fully rotate them.

Joe, You don't have to ask anyone, but if you don't do it by the book, and sell the car to someone who gets buyers remorse and claims fraud, you could wind up getting visited by the feds. I don't live there anymore, but I lived in NY years ago, and know people whose cars were seized for that. I also knew a speedo tech who went to federal prison for spinning clocks for car wholesalers. In this litigious society, better safe than sorry. All states vary. Florida marks antique titles (over 30 yrs. old) as Exempt. AZ requires you to note "True mileage Unknown" on the title if you alter or replace the speedo. They check mileage on annual vehicle inspections in AZ. Some states no longer issue titles on vehicles over twenty years old and are Bill of sale only. I am sure, as you note that every state is different, but an ounce of prevention is better than a pound of cure. what's one more piece of paper in the file?  My current titles are all marked "Exempt" by DMV.

There's a local collector here in our town with an absolutely gorgeous Detomaso Pantera that has well over a hundred thousand on the clock. He's had it for years, and drives the hell out of it. He also claims it is the only Pantera around with true mileage, as he follows the market, and sees the other cars repeatedly come up for sale with artificially low mileage, year after year. Truth is, if it's a fun car, who cares. If you put it out there as a valuable, special piece, it had better be with every "T" crossed and every "I" dotted. Was it Seinfeld, or some other celebrity who just had to buy back a very expensive Porsche Spyder, because the buyer found a minor defect in the title, sued, and reversed the deal. My original point was, better safe than sorry. In the end, none of this answer's rag's original question, of how to do it.
