I'm going to change the shock disks on my C model soon and I was looking for the tools to do the R&R. I saw the tool available from Hangar Toolbox, but decided since I make tools that I should just make my own. I'm on target for making my prototype for less than the cost of shipping for a rental. I'll post back here how well my tool worked or how well it didn't.  David     attachment=26324:M20 tool.JPG]
