Yesterday in my junk yard dive I noticed the 4 door cutlass cruiser, I was not so lovingly harvesting my frame horn out of, had to extra sway bars, or supports that run over the front sway bar to the cross member on the frame.... I didn't see any two doors with those supports however, all corresponding bolt holes where there. I harvested them, obviously. Do these help at all? Where they only on the four doors? Or earlier years....
