Installing distributor bushings-without "tools"

[Fred K-OR]

Can anyone give me some ideas on how to insert or install the bushings in a distributor without some of the tools that are shown on some of the posts on the Barn. I have none of this type of tool, only a hammer and/or a block of wood. In other words I know nothing about what I am doing. Tom Endy's post shows an insertion tool to use to push the bushings in to the body. But I do not have any of these tools so is there a simple, safe way to do it without destroying the body?
