A100 Build dates

Hello from Scotland. 

Can anybody help me prove the build date of my A100?

I can't get my van registered here because I have "not given sufficient dating evidence" even though I have provided the California title etc showing the 64 build date. 

Is there any way I can narrow it down??

Thanks,

Hugh

on your vin plate the last 5 numbers will tell if it's a 1964   000001 thru -014999 . http://missiondetail.com/vin.htm

I know some one who worked the assembly line in detroit mi. if needed i can contact him. to see what he knows. And he knows a lot...

Dix just got hold of me.
 Didn't see you come back with that VIN# and I would need the one STAMPED on the Rt frame rail just behind, or just ahead of, the rt front shock?
If you can't find it for whatever reason, I'll accept the one stamped into the ID tag in the Lt Frt door opening. 
Build dates were sporadic at the least, in summer of 1963 getting the first 1964 A's out the door at Dodge Truck, Warren Compact Building.
I also can't imagine why any jurisdiction would need an actual Build Date unless there was/is some question with the validity or originality of your factory riveted on ID tag?
If there is NOT an ID Tag - just the 4 holes where it used to be - THAT may be their question.
Go to the SN# stamped into the Rt frame rail. 
Please Note:
1. There was NO Build date on the Factory ID tag.
2. All build sheets were removed from Dodge trucks before they left the plant.
3. If there WAS one left in there it may be taped to the roof behind the headliner or stuck to the bottom of a rear seat, such as in a Custom Sportsman. 
In a Tradesman Van or Pickup the chance of ANY build sheet surviving was slim to none.
