I agree about the newer cars, but I don't think reproduction parts for a fifty plus year old car will have high dollar synthetic grease. I think they'll have the cheapest crap in them money can buy since it's a kit and they cut every possible corner known to man in the name of profit.
I can't argue since I wont cut a new part open to see what type of grease is in it. There isn't 2 whole tablespoons of any type grease in a ball joint.
