I did the same thing. With the lid on, you can't tell it, even if you know where to look for the seam. If you have the filter in hand, you can tell what was done.
I just took my time, and cut a little off each time. And the best part? The price! It was $18. and some change with tax. Still haven't found anything that is drop in. Found a few K&N's but they are taller- 2.5 and 3." These will rub either on underhood support or sound blanket on some Demons and Dusters. That's one of the reasons Mr. Norm used these filters and air cleaners, as they were a drop in part from Segal, and no R&D costs. And the K&N's aren't as cheap as the Baldwins.
