Wayne's c4 frame
 

I also have one of Wayne's C4 frames. Just comparing pictures of The Mule's frame to mine I can see that Wayne lowered the mounting points on the frame for the upper and lower A-frames. Would that have been to help with the rack geometry problems?

^^^X's 2, My WD looks a bit beefier on the frame rails as well.

Thank you Mark for chiming in and clarifying a few things. I look forward to dialing in my suspension in the future.

any updates on the c4 front? if your still not wnting to go this way pm me please. ive been researching this for my 1956

I noticed this thread sort of died out a couple of months ago. I just scanned back over it and I don't think anyone mentioned (even Mark Stielow himself) that Mark's book "Building the Mule" has a ton of photo details how to make the similar Rasmussen clip work. Of course there are newer designs and that is clearly mentioned in the book. However, there is a ton of good detail in there to make this work pretty well. Not everyone is the same. Some prefer to buy the latest design and others would prefer to fabricate and learn as they go along, making each project a little better than the last. If the later is interesting to you, I recommend the book as it is a great resource. In fact, even if the Wayne Due clip is out, the book is still a great resource and inspiration.
