Mopar Rally wheels or Cragar SS

As you can see in my avatar I had the SS's (circa 1976). Man those things sparkled when they were rolin down the street. I had corrosion problems on my original wheels almost from day one though. Always wondered about the cast center steel rim, galvanic action maybe? Got my second one in 85 after I totaled the one in the pic, promised myself I'd never have another set. I restored some rallyes for my newer one.
