This is the strongest! That's right, this is it, the large 26 clutch spline, M22 input shaft used from 1970 - 1974. M22's were all 2.20 to 1 ratio, so that's what this is, again from the best in the business. We offer this in 10 spline as well but you will need to call as we do not put them on the web, we believe strongly in using the bigger, stronger, 26 spline in ALL applications that are M22.
