This was a pain because the six Hex Bolt M8-1.25 x 16mm were too short. 16mm = .63 inch which was slightly too short, I went to home depot and bought some longer M8 bolts that were 1" 1/4....(1" would of been fine but I wanted to be safe).
Now this part was also annoying because I had to run to Home depot because the six Hex Bolt M8-1.25 x 16mm did NOT fit - they were slightly too big (see photo below).
Extra pieces required:
- six M8 bolts that are 1" 1/4 in length for motor (you will need bolts but you should have some with kit)
- six 5/16 x 3/4 bolts and nuts (you will have to drill 6 holes with a 5/16 bit to make holes slightly bigger)
