tti header clearance problem

Called spoke with sam at tti, explained my problem he tells me that he has heard of a tight fit on the rt side the passenger side but not the driver side lt, he states to loosen the motor mounts at the engine side of mount upper and the frame lower side nuts on both sides and move the engine back he states you should be able to get a least 1/4 space then as needed i will give that a try.
