Looks good!, I did my '68 goat 'vert a couple of years ago with the those kick panels and installed the same Infiniti speakers, smart choice,
I like the adjustable tweeters, and they even sound good too.
I purchased my kick panels from Custom Autosound, I have seen them in parts catalogs too. I have a Pioneer head unit in the glove box and a boat remote hidden in the ash tray so I only have to access it to change CD's. My Vista Cruiser will have plenty of room for a more substantial sound system, a big plasma screen would fit right under the storage compartment lid.
