I was simply stating my opinion. Ive been to the dmv twice, once when I registered it and once after this thread. The SHERIFF at the counter helped me. Told her my concerns she said ''If the title was not already exemt it would,like EKfour stated, have to be taken to a certified mechanic and a sticker on the door jam, But if it is exemt there is no way to verify the milage so it would be very hard to determine who put it in and told me not to worry about it'' and if the feds have time to single me out for buying a cluster and not spending 100 bucks to have it put it in so be it although the cluster in it now has 5000 more miles than my old one and I still got it for proof, pics before I took it out and when I first bought the car and the pics from when installing the new one FOR A TACH take me to jail for screwing myself.
