you would have an angled two link with no articluation.
sorry, its the solid rear mount that kills it.
Here is how I explained it before:
Get three 2x4s and two friends in tennis shoes. Lay one 2x4 down on the ground. This one will be your axle. Lay the other two like two link bars from the end of the first, perpendicular. Nail the "bars" to the "axle", this simulates the solid mount of a two link when you bolt it to the leaf spring pads.
Now have your two friends stand on the other end of the "bars" so only the fronts of there shoes are on the 2x4, their heels should be on the ground. This simulates the bushings at the frame end of the bars.
Lift the axle 2x4 from the center. Goes up and down, nice and easy. This simulates BOTH rear wheels going over a bump, like a speed bump, that is equal on both tires.
Now, lift the axle from just one corner. OOPS! both sides still come up equally. This simulates what happens when only ONE wheel goes over a bump, both wheels will still react to the bump.
To simulate side to side, lift one corner of the axle and have a third friend force down on the other. The friends standing on the bars will tell you the 2x4 is trying to twist out from under their feet. Keep forcing, and the nails will start cracking and popping or the bar will yank out from under one shoe or the other. This simulates the real forces that are on your axle mounts and frame every time you hit a side or pull into a sloped driveway at an angle.
