If you have recently, or plan in the future to replace your 2015 Mustang's stock hood with an aftermarket fiberglass hood, a new pair of 2015 Mustang hood lock & pins should also be on your mind. Fiberglass hoods are incredibly light, much lighter than your stock Ford issued hood, meaning that it is much easier for them to come loose from your stock hood latches. With decreased weight comes decreased strength and durability, which is why fiberglass and carbon fiber hoods should be properly secured with the use of a set of hood pins & locks.
