Thanks for this tool Klutchmaster. I could have REALLY used it about three weeks ago when I was trying out a new spring combo on the sedan/deliver...but I'll be putting one together for "next time".
I would also recommend that you go over to this thread
and include this tool on that collection of useful hand-built tools. You could either copy the pics and text from here over to that thread or put a link in that thread to this thread along with a brief explanation of the tool. I think a lot of folks would find it helpful.
