So this not spool type mount? This is what I did. 1/4” steel sandwiched between the mount and the k frame. With fingers that can each behind the motor side mount.
I think I will weld washers on that driver's side mount, centered with the new holes I drilled. That will strengthen the mount, give me some comfort over that flimsy looking notch/weak spot...and a torque strap. Thanks all.
