George, without seeing what you have at the moment it's going to be very hard to say whats needed. Is it just a chassis, or chassis with axles etc, or running chassis with engine.
This will show you how to add photos to your post
Your best bet is to either buy a set of drawings or the old issues of ME that covered the build, you will need them anyway for the bits you mention above and then you can see what else is missing.
