Looking for 70 Dart info with missing fender tag.

Unortunately without a build sheet or an IBM card or the window sticker you are most likely out of luck.

The vin will give you the engine, factory and a few more tidbits like if it was a high medium or low dollar car.

Basically without the other info, the build of the car is lost.

There are people who claim to I have the records but I would be sceptical if you need to plunk down hundreds to get it.
