sub-frame and headers




Rear sub-frame before final disassembly for media blasting, primer and paint. I also rebuilt the brake calipers. The differential was gone over with a cursory inspection, new out-put shaft bearings and seals, new pinion seal and a finned aluminum rear cover with a new gasket. The half-shafts received new U-joints. The hubs received new bearings and seals. The shocks are a set of old Konis with temporary ride-height maintaining spacers. They'll be replaced soon. Most likely with a set of externally adjustable VariShocks with new springs. I'm still waiting to see how much heavier the car will get before chosing a spring rate. Right now the car weighs about 2,000 lbs assembled. The brackets on top of the sub-frame anchor the roll-bar braces. The new, longer inner fulcrum shafts for the lower control arms also anchor the bottom of the sub-frame to the chassis. The upper shock bolts also connect to the chassis.
