quick question concernjng driveline?

[brassnutz]

Does anyone know wether this setup might have a 16-16 (lenco) coupler at the opposite end of the driveline, the adapter at the flywheel is 10 spline. I've seen sprint car drivelines with 16 splines at one end and 10 splines at the other end. My casale has a 16 spline input shaft.........

That is a Casale type solid driveline, the coupler is not splined it's keyed just like the prop shaft!..
