New as far as I know anyway. What I'm going to do is use 2 lengths of square tubing per side. I havn't decided if I wanna use 1.25" or 1.5".

They'll be welded together, both weld to the same place on the rear subframe. They'll go up the body, stiched on to it every few inches. But, when it gets to the front subframe one will split off in a Y and they'll weld in at 2 different spots. I might even tack on another support leg, making a K shape. I'll make a straight piece up to the front of the subframe near the tranny bellhousing, while the offshoot of the Y will go to the very rear of the front subframe.


Opinions?

Just copy everybody elses designs. The "K" sounds like a little too much. The "Y" design is probably the best. This is what I'm gonna do too. But I'll just copy the aftermarket.
