The frustration of being an 1/8 inch started with the builtins in the family room. Our plan was to take the cornerr unit out and put the regular book shelf in the spot so the fireplace had symmetry (I love symmetry). Also the corner unti was not going to fit our TV. Well the regular book case was to big by an 1/8 of an inch. These untis are solid oak and built to withstand a hurricane, so once again no quick fix was able to make the until fit. Therefore, the second picture is what we are living with for now. I think I don't mind it or at least I have just resigned to the fact that this is the way it will be for awhile, until we can get the bookcase cut down to fit.
