The emblem can still be ordered from the factory, but I wouldn't put them onto the side since only these first cars had them there.
The series car had the jalpa badge only at the rear.

They weared white and black badges matching to the colour of the car. Silver and gold was done by the owners as far as I know.
The jalpa badges are made of brass, the bull sign of aluminium.
