68 Vert Wheel Fitment Question

[Blue Oval Man]

Love the look. Looks like you would have room to go a little wider in the back, either in rim width or tire width. How is the clearance on the inside?

I'll take a picture. There is a fair amount of clearance in the back. I'm a little worried about the outside edge, but I think that's because my outer wheel well was put on wrong. New wheewells and quarters will be put on, the last guy I had working on it butchered it up. He was rushing in the end, which is why my car came back home.
