Identity Crisis

[Martin64]

This really is getting funny. When I bought my truck, the guy sold it to me as a '64. I look at the registration and it says '64. It has a '65 badge on it. A local guy says it's a '65. I get the "pink" for it today it says built in '64 and 1st sold in '64. I run the VIN on 2 different sites today and one says it's a '61 built in Flint and the other says it's a '61 built in Canada...... I'm not going to lose any sleep over this, but I'd kinda like to know what I have. Should I take the DMV's word on it since they seem to be the most consistant? Is there such a thing as maybe a '64&1/2 that would come with a '65 badge? How do they get the peanut butter in a Reese's Peanut Butter Cup?
