May not be what you want to hear, but I would remove the motor and transmission and install the "K" member first. It would be easier to adjust for placement. I have installed several "K" members that way, without issues. Note: Be sure the ends are cleaned out and with fresh grease added. Remember, there is a left and right bar and make sure they are not bent or nicked. Adjusting bolts are down or relaxed, then adjust for height after power train installed.
