Don't believe so. There was a run or two of the Boss - big suspension but those wouldn't be for your application
There have been a couple of thread discussion of aftermarket two piece rotors but those focused on earlier versions.
Same goes for rear drums - aftermarket ones are available but you would have to compare their design to originals. Of course they will not have the original markings on the outer surface. Maybe someone else has gone through this process recently and can offer their findings
