re: dropped spindles
FWIW. You didn't mention the application, but, I just got a pair of 65 - 70 chevy dropped spindles from CPP (Classic performaqnce Products), very impressive. beefy enough to support a tank. $239.00 alone. They came in a kit that included disc conversion brackets, rotors, calipers, bearings, seals, nuts, washers, cotter pins, dust caps, flex hoses, both 7/16ths and 1/2 inch mounting bolts for the steering arms. I didn't need a single extra piece. (bearings were prepacked) The kit was $499.00. First kit I've ordered that I didn't have a single problem with.
I'm always hunting a bargain, but I draw the line on brakes and steering.
