Nissan used some change trays that were designed to fit inside of a DIN sized housing in the 1985 200SX and probably in other Nissan cars as well. I It has four screws that hold it in. It slides into the slot really easy with hardly no protruding lips and does not need to be screwed in.

This is what I am using in my 1972 Datsun 510 and it works great.
