Stop in for a cup of coffee

Not sure how that is formed inside...Couldent it be spread out or reamed out that little bit?

If I had the tools yes. Either turn a bolt a little bigger and press it down on the bolt, or use one that fits and then hammer it outside a little until it is big enough. Still would be fun to know how it is supposed to be. I can not remember it being extremely tight on my first Dart.
