Spindle nut kit for valiant

I have a 67 Valiant that had a slant 6. The car has been sitting for several years and during that time most of the suspension bolts are gone including the nuts, washers, pins, and cover plates for the spindles. I'm trying to find these items through the regular parts stores with no luck. I think the car had 9" brakes. The spindle nuts are 11/16" not 3/4" which is what the parts people keep giving me. Any help out there? Thank you, Bill
