Difference in Fuel Tank- 67-69 BCuda Dart vs 71 up Duster Dart

[chickendeluxe]

CAN I use a 71 UP in a 67-68 Barracuda?

The tanks are listed as Specific between years? are the fillers the same?

or is this just ventilation tubes that make for different tanks?

Thanks

I believe 67 was single strap mounting that went left to right instead of front to back. Im not sure on filler hole differences but if I had to guess that will be the same. There were also differences in tanks such as emission ports.
