Note: These clamps are made by Wittek which is who Buick sourced back in the day however we feel these clamps aren’t quite the quality they use to be. For better results lubricate the entire clamp prior to installation. This helps the clamp tighten down properly. The lubrication eliminates some of the resistance during the tightening process. Make sure the bolt stays straight during the tightening process as well.
