Thank you 4ePikanini, but the bolt wasn't questioned as it was replaced a month ago with the new one. Unfortunately the dealer's mechanic did not torque the new bolt down properly, so it started backing out yesterday and snapped the pin, reference number 03789 in the diagram you provided there. Nobody (dealer, Napa, Autozone, Checker) could seem to find the pin based on that number nor my description. Motero says any rolled pin that will fit should be fine, so I am going to go through the hardware aisles of Ace and Home Depot in just a little bit and hopefully that works out.

If anyone knows if there is anything special about this pin and why I should search harder for the "right" one, please let me know right away.
