It is hard to find the right motor mount bolts for the 116 diesels. They have to be good hard steel and just the right length. We have provided locking washers to install with the bolts so they will not loosen up. When these bolts loosen up due to diesel engine vibration it will ruin the threads in the aluminum motor mount arms. Requires a 10mm hex socket to remove and install ( see below).
Fit only 1978 to 1980 116 300SD Diesel engine mounts.
