 The MoCo's first use of grade 8 motor mount bolts was in 1986. \\
-===== Torque Specs =====
-There are no torque specs for the motor mount bolts in the 57-78 FSMs. \\
-And there is only value in the 79-85 FSM (rear motor mounting bolt-nut: 16 to 24 ft lbs). \\
-For the rest, there is a "General Fastener Tightening Specifications" chart in the 70-78 and 79-85 FSMs. ((1970-1978 HD Sportster XL/XLH/XLGH/XLT-1000 FSM pg 1-13)) \\
-It lists general torque values for bolt types but not specific mounting bolts. \\
-It also says to torque to these values given in the table unless specified otherwise. \\
