Points #580148; condensers #510173 replaced by #580321; coils #580118 replaced by #584477. These numbers are the same for the ’56 and ’58 Johnson QD motors. The marineengine site will give you the corresponding Sierra numbers for each piece. You should know lots of us have experienced trouble with proper fitting of the Sierra point sets and the new BRP point sets aren’t much better. If you can possibly salvage your existing point sets with a good cleaning you would probably be better off.
