Hey everyone, I have been slamming my head against my desk all day regarding this and I haven't been able to find any information any where. I am wondering why or how there would be no vin number here. I have heard of motors having their vin filed off but never dots placed on top or anything. I recently purchased a 71 cl350 and an extra motor. Now the motor on the frame does have a vin number but the extra engine has dots where the vin would be. The dots look all the same size and in nice little rows. The guy I got the extra motor from couldn't tell me anything about it but it looked pretty clean and wasn't seized.
