Any bolt with the correct thread and filed down and screwed in will do the same thing.

None of my previous cars have had a guide pin in the hub. Because of the wheel balance issue I did what mjk164 has suggested. Mark the wheel and hub or stud to ensure that you replace the wheel in the same place relative to the hub.
Decades ago, before front wheel drive was so prevalent, there was system for dynamic balancing of the front wheels whilst still fitted to the car. This method factored in any imbalance of the brake drum/disc and hub etc. IIRC, the wheel was jacked up, sensors were placed on the suspension, a trolley was located beneath the wheel which was spun up by a wheel within the trolley and a result displayed on display on the trolley, then weights added as required. Having gone to this bother, if the wheel was subsequently removed then it must be replaced in the same position relative to the hub etc. or the whole thing could be out of balance again.
