There's some pretty good shots in the custom rigs section of our page, just imagine your pitman arm where my idler arm is and you'll be able to get it put together. I doubt mine would work with leaves though. The pics I posted before are about as good as it gets with leaves and a panhard. The only thing I would do different is stick the driver's side of the panhard outboard of the frame rail a few more inches to make it closer to the draglink length.
Jason, (zcar) if you're building a frame, DO NOT stick with the leaves. I know what you want and it's not leaf springs. Go to coils. I have some ideas on ways to make leaves work well for long travel systems with panhard bars and by the time you're done with the monkey motion you might as well 4 link it or run some radius arms. The only reason to keep the leaves on a high level fabricated vehicle is for the rules. If you want to race class 3, we should talk about some different ideas using leaves, otherwise, join the round spring crowd.
