Tallon I know what you mean on the shoulder and believe me it bugged me too, but to correct that would be a huge project. You would have to sand down the lip (with a long staright edge) so it is straight again, correct the pitch of the rear quarter, add material to the lip with a combination of fiberglass and duraglass. I mean It def can be done but that would be a lot of work. Ive learned to just live with it.
