70 Duster 340 without Rallye Dash?

HI FABO,

I just bought a 70 340 Duster and everything looks good except on thing; it doesn't have a rallye dash. As I understand it all 340 Duster's were rallye dash cars. Also the fender tag for this car has A62. I have the fender tag and the vin is on the dash and inside the door. The body numbers match the vin and don't appear to be monkeyed with. The engine and transmission numbers also match the vin. I can see the car was originally and EF8 car which matches the fender tag. Plus a lot of the other fender tag options appear correct to this car. I suppose there are only 3 possibilities:
1. The car is a rebody
2. Somebody took out the rallye dash and riveted the vin back onto a standard dash. That does make a lot of sense to me but you never know.
3. Factory mistake? Has a 3/20 build date, is it possible they ran out of rallye dashes (I know that a stretch)?

Any info or thoughts would be greatly appreciated.

Thanks,

Steve
