for the ashtray, go to a junkyard and look into the bakk rear passenger seats of a 87 lude, the side rear passenger ashtray is the same one used for the audio console, i know cuz my gf sister bf has a 87 lude and i pull the ashtray out and fit it on mines, perfect match.
for the console ideas, get the lower din a pocket out of the 6gen accord coupe, its a pocket and has a door lid. the top, keep it blank and add gauges, vafc, ect.
