Default Using Watts linkage with 3 Link Calculator

Getting closer to actually starting this buggy. I am going to have a triangulated 4 link(still doing the math if the lowers will be triangulated) in the front. With a 3 link in the rear running a watts linkage. It is a rear engine setup with the balancer 5" in front of the axle tube and more then enough room for almost any upper link frame mounting point. I bought a second medium truss for the rear and plan on having the top of the truss be the rotation point for the watts which will allow for more travel.

I am playing around with this 3 link calculator getting nice results using the set panhard measurements. What I can not find any info on is how to get this 3 link calculator to figure for a watts linkage and not a panhard bar.

I am sure I will do a lot of tacking, lifting, and checking when I do actually link this before it drops how I want. But, if I had a place to start from using this calculator it would cause less headaches. I have a little over a week to play around with the numbers if I can get this panhard bar issue figured out.

If I can not use the calculator I will build a mockup in Inventior and have the links set with parameters and hole positions which i can change which should work for check binding and flex but will not show any stresses or squat and roll. I might be able to add force's to the frame and stimulate hard acceleration, breaking, or cornering but I am unsure at this point.

Any help is greatly appreciated.

It's not on the calculator because nobody runs one. Every other person runs a normal, easy to build, panhard bar. Why do you have to make everything so difficult?

So, you have the engine in the back, a triangulated 4 link in the front, and a 3 link in the rear....

Can't you just take a nromal trail Jeep and drive backwards? Same thing....

You guys are all idiots. Don't you know that a normal 4 link doesn't have nearly enough flex? Once he gets his figured out I'm going to ask him to build one for me.
