Well
I'm 98% pos that magnums have the same recess in the crank if I'm wrong someone step in so if my other magnums use the spacer and roller bearing then the input shaft on the trans should be right for the bushing since it is a magnum nv3500hd . But I will check that! Just so someone reading this is aware that the input shaft problem that teringer is referring to does apply for all the la motors cause they were produced in different dimensions so the fix in this thread only applies to magnum engines and maybe some la's but NOT all
