Need a replacement case back

[sphinx9mm]

Hi all , New to the forum and to a Rolex watch. I can use some help here. I recently acquired a Rolex Oyster Perpetual, model 6567, movement Cal 1030 manufactured 1957, ser.265xxx, The case back had a hole in it and was repaired what looks like silver solder. I would like to replace the case back and have seen a lot of used case backs on Ebay. What I would like to know is, are any other model case backs compatible with my model 6567. You can't see the repair when you are wearing the watch , just bothers me knowing it's there. Thanks all
