I recently completed a full restoration on a 1956 Johnson RD-18 that was originally a manual start model, but I added electric starting in the restoration. The correct starter bracket with the front cowl support pin you need is OMC part #376885. That bracket was used on the 1957 Johnson 35hp but will bolt up correctly on your 1956 model.
By “cover over the flywheel” I assume you mean the complete manual recoil starter. That is OMC part #376663.
You might find the electric starter bracket and recoil starter by placing an ad in the Classifieds section here on the AOMCI site, or maybe on Ebay.
The gearcase seal kit is Sierra 18-2686. The complete water pump kit is OMC #379774 which includes impeller, lower plate and a new impeller housing. Kit #379767 includes a new impeller only. The carburetor overhaul kit is OMC #439074.
The gearcase, water pump and carburetor kits can be found on marineengine.com
