Flip top cap on a dart

As far as the mechanical layout is concerned I don't know if there's a difference. In appearance, yes. But I think they all fit the same. And if you have to make it fit anyway, I'd go with the one you like best and make it happen.

I saved the one that was on my '68 Barracuda and welded the sheet metal pocket into the quarter on my '72 Duster. Lower profile and I think it'll work out fine.

Between the Charger and Barracuda flip tops and the model year there’s a few minor changes, like the bolt pattern to bolt the cap to the body, whether or not there cap says “fuel” on it or is plain, and whether the cap is set up with a spring and gasket to seal the fuel tube or whether it was set up to have a fuel cap under the flip top.

But pretty much all of them will work with the adapter.

I have some extra flip tops, if someone wants to message me about them so as not to make this a for sale thread.
