Miser, In the vid you rubbed one of the pins up and down like. I know you might hate to mess up the finish in those 4 areas now, but no better time to do it with such good access, and before they get damaged. Reinforcing them as Justin described above not only gives peace of mind, but if ever in the future you modify the engine for more hp or performance, your differental mounts will be up to the task. Solid investment all around - great selling feature too if that ever happens.
