Compatible Grille for 85 Eldo Biarritz

Looking to replace my plastic grille with something a little more rugged and stylish. Can anyone point me in the direction towards what other caddy grilles can be worked in. I have seen some of the high profile classic grilles but at 600 bones I am unwilling to commit. I don't mind doing a little modification to the mounts if needed. I contacted my local dealership and they were basically useless. I am especially curious about some of the 80-85 Sevilles. Any help is greatly appreciated. ,B
