A 3 foot rod of 6m will flex. Most things that long and that skinny will. When I re-studed my engine I made sure that the studs were snug but not super tight into the motor. that way they weren't completely bottomed out.I also used blue locktite on the motor end and lock washers and double nuts on the bracket side. I'm no expert on these by any means but (fingers crossed) I have yet to snap or strip anything. Thanks and good luck! Evan
