I converted the R53 over to a non-armrest setup, and saved the full assortment of armrest-related parts. The armrest itself has some scratches and the lid needs to be replaced because it won't stay shut, but all the parts and hardware are present. Price: SOLD I also have an R53 cup holder available, as well. Price: SOLD
I'm hoping the cupholder will keep my wife from driving me battier when we take the R50 out and about. Now, she will have a place to set her beverage, instead of holding it on her lap [the dog thinks that is HIS domain and only HIS!]. Thanks again, Zack!
