These were mounted to a set of 1/2 shafts I had purchased some time ago. Splines are perfect. You can have the 3 boots and associated hardware if you like. Boots are not torn and still pliable. They are the 4 hole versions, but are 40 years old. $55 shipped. I think I have a pair of gaskets I can toss in. Plus a 2.0 throttle body gasket.
