Well, haven't found the dimensions for the factory bezel yet. Have seen enough posts that say it looks great with aftermarket HU's and using a couple 1/8" spacers. Guess I will bite the bullet for factory bezel (non-bose). Audio store told me Nissan has a deal with Clarion for the double din HU's that are made for them. Hopefully, that means the opening is a standard size. Haven't seen any for reasonable cost, though.
