Hi Mike
Getting hold of cromodoras is not a problem. Superformance do them in either the standard 14" as per original dino or 16" for dinos with big brake kits. Silver or gold too.
The problem is getting then to fit the lada/fiat front hubs and the lancia beta rear.Try looking on the changing to 108pcd threads on here
It's something I'm working on myself,as well as upgrading to monster 4 pot wilwood front brakes and 280 dia 25mm thick vented discs.
