Well Joe just an FYI on the Hellwig, its actually a 3/4" bar not 1". Summit just has it twisted. Im not even sure the Hotchkis is 1" but either way if I had to bet id bet on the Hellwig being lighter. And if you punch in that part # to Amazon you will save a bunch on that Hellwig. I found my Hellwig 6908, which is an Ebody rear bar but still works on an A body and is 7/8" instead of 3/4", for $140 shipped on Amazon. Oh another thing is the Hellwig end links mount to the inside of the frame rails so they work with my car having the springs moved in 3" per side.
