Moss has the glove box lock. I think it requires a little fitting though.

I think all this goes back to cost. The wiring harness and components are nothing like the original but the cost would go way up to make it accurate. Wipers park on the wrong side, wiper motor not correct, gas cap not accurate, switches not correct, glove box door shape, shape of the dash, leather on the dash not shinny enough, gauges not correct, seat sliders wrong style, shifter too tall, turn signals wrong color, ... you could go on and on but it IS a production car and not a home built. To produce a car now, accurate to an original would add tens of thousands per car, if not more. Plus the parts are just not out there in many cases. Not anymore anyway.
