I too have slender arms and hands but my biggest challenge still was finding no position for the wrench to loosen. It could very well be doable with an assortment of the right tools and resolve. The torque spec is 26 ft lbs. so its on pretty tight. Conversely when the OFG bolts are removed you can at least turn and tilt the housing toward you to get to the bolt easily.
