Strange VIN?

[Jimmy4765]

I've got a 63 C10 that has been in my family for almost 30 years. It's in AZ & I am in Iowa. My dad is trying to get a duplicate title for it because he lost the original who knows how long ago. The truck hasnt been registered since 01 (?). He went to the DMV & they told him that the truck has never existed in their system & they can't issue him a title. My question is, can anyone decode this vin? It's been on the truck since the 1st time I saw it (92) & hasn't ever been tampered with but when I try to look it up, I can't find any info on the 6th digit. Has anyone seen this before? Thanks!
