Nothing in the thumbnail
I can't see this working. You want the upper link above the pumpkin to extend forward, not rearward. What you have proposed will likely pull down on the rear of the body, which means in essence it is lifting the tire away from the ground(same as "squat" in drag racing, which is an undesirable condition).
