Hi juvela,
Thank you for the suggestions. Actually, it is more in the way the photo is reflecting the light & shadow on the seat binder ears. They are pretty flat and take a binder bolt just fine. I did do some dremel tool work on other parts of the frame (leftover braze material) and sanded it all smooth.
And an update: I fixed my white downtube section over the weekend, so now it sits higher up as it should. I had to sand down some orange paint, respray in white, and readjust the section. I am now on my 3rd coat of orange, with one more coat coming for good measure (with sanding in between every coat). Once the paint cures, decals will go on, and then a clear coat.
Moving slowly but surely. Pics coming soon.
