35 spline would be more than strong enough for that combo. I would look at Strange instead of MW. MW uses a oddball spline angle and is not compatible with any other manufactures parts. Strange makes a great product and supports sportsman racing with their Perfectly Strange program. I have had their axles and spool in my super stocker for 20+ years. Get them with the 5/8 studs too.
