68 dart gas tank leak

You can get this on Amazon by Saturday. I would use my original lock ring for sure with the gasket.

Doesn't sound like it's too stock of a vehicle anymore.

Thanks Rhonda,asides from the engine and transmission (727) everything else seems to be original. The car was originally a 273 v8 car and has fhe V8 badges on the front fenders. Interior is stock. Even all the factory air components are hooked up. Not sure why the engine was changed.like I said it’s hard to find one of these that hasn’t been messed with or hopped up. I’d be just as happy with a 318 or 273. Tomorrow I’m off work and will have time to get under it and check things out. I appreciate everyone’s help here.
