The NT-37 front windows, windshield wiper motors, etc., are very hard to reach. I used a 23 7/8″ x 8″ piece of hardwood (birch) to make a step supported by 1 3/8″ battens either side. 8-10 screws either side support the step very well. The step stows between the portside seat and the bulkhead. Can provide a photograph of it stowed.
