Hello everyone! I got home in my 57 One ton step van (saga story to be submitted soon)and the engine seems pretty worn out. So I purchased this engine on ebay hoping it is a good replacement.

This engine has a foot switch for the starter. Will my ignition switch starter replace this setup? Is there anything I should be aware of when switching the engines? Thanks for your time and any advice you can provide.

Here is a pic of the step van.
