Thanks for the pics! My car looks just like yours from the back. I also did a US Car Tools chassis stiffing kit. I am putting on QA1 tubular upper control arms, 1.03 PST torsion bars, 1 1/8 front sway bar, for now a stock rear sway bar (probably will need a bigger one down the road), stiffening plates on the lower control arms, sticking with the stock k frame. I am planning to put in a rack and pinion and hydraulic clutch as well. I am planning a 408 stroker with a four speed.
My work is not quite as good as yours, but I am having a blast and getting better everyday. Your forum will really help me.
