Rear control arm incorrect for 64 442. Should be fully boxed for nearly one end to the other. I’m starting to think something was tweaked along the way. Would be helpful to see the holes for trunk and fender emblems. Would be nice to know the rear axle gear ratio, which should be 3.36; although Motor Trend did test the car with 3.55s and that does appear in a couple of documented 64 442s.
