I have the same problem with my 75 Spider center console (large Ashtray). It has broken away from its attachment bolts. I have been told its best to attempt a structural/cosmetic repair instead of buying an aftermarket unit.
The reproduction sold by IAP is good quality and looks good, BUT it is Euro configuration. It is designed to have holes for the shifter, the round hazard switch, a round brake warning light and three rocker switches (no dimmer rheostat hole). It could be modified to accept the rectangular idiot lights on the SPICA cars but it would be quite a bit of work. It is a good replacement if you have Webers.
