Yes they really wanted to be safe I guess. My old '65 mustang took 5 minutes from the top. That's ok, the one in place is original. But has a big split in it. I was just trying to quiet it down until the big show. No biggie... Found the other weights, there are about 18 or 19 that are correct. So I feel better that it's a good start. I wanna be standing there with the weights in my hand while the new tires are being mounted. But like Charlie mentioned, I can just go back and do it myself with the matching size weight later if I miss 3 or 4.. D
