hi i am restoring a metal slat grill to fit to my 93 sprite but im unsure if the metal backing i have taken off is needed , as all the grills i have seen on google have just been open backed. so i wondered if maybe this was for a mpi. i have included a photo of a similar grill and then the backing in question.
same style of grill this also has the backing but is it best on or off (this image is off google apologies if its someones on here)
