    I have a 78 chevy k20 with a muncie sm465 and a divorced 10 spline np205 t case. Driving down freeway noticed something in the drivetrain trying to bind or lock up, slight and quick shudder. Well long story short, parked the truck in the garage and here it is two years later and finally pulled the t case. Front input bearing missing almost half the bearings. There not in the case and it was moving and driving when i parked it. All the gears look ok except the output shaft gear. Now im having trouble finding a 10 spline output shaft. Can find 32's all day long. Can i just put a 32 in it and get a different yoke? I heard the early 10 spline 205 used a 80mm bearing and the later ones used a 90mm and would the seal be a different size also
