As most know, I build minature versions of the real monster trucks. I am currently working on a full blown 4x4 version with 4 wheel steering, designed for younger generation excitement. I wanted the over all length to be 8 feet, my question is, how do I determine where the center cradle should go? I would like all the 4 links to be the same lentgh, but for some reason I can't get them, the front is longer than the rear. Any help?
