If your package arrived and there were items missing form your order, it is possible that the missing items were unable to be shipped at that time. Most commonly, the items were out of stock at the time the order was placed and we chose to split the order so that we could get you the rest of your items sooner -- instead of waiting for the out of stock items to arrive. If this is the case then those items should not be on the packing slip you received with your package, and we will be shipping out the remainder of the order as soon as we can.It is also possible that there was a mistake made on our end when packing your order. The clearest indication of this would be if the count on the packing slip does not match what was sent. If you believe this may have happened please contact us at shipping@fire-Parts.com and we will try to get the missing item(s) out to you as soon as possible.
