suspension diagrams


I'm looking for suspension diagrams for I beam and solid axle suspension systems. I am going to be giving a 15 minute presentation on the different types of suspension and multi media would be helpful. This is just a class room exercise so it is not an in-depth discussion. I already have one for A-Arm suspension similar to the pictures found on the Total Chaos site. I've looked through a history of stuff on here and I've only found links that don't work. I don't want to spend a week looking for two pictures. Thanks for your help.
