Beware that some of the output splines on a bolt on yoke have splines missing.....to force the orientation (phasing) of the joint. If you have a bolt on yoke tranny, unbolt the yoke and try your slip yoke on it.....you need at least an inch or so of travel. Make sure the seal area diameter is the same for the two or else you will have a small mess. If you have the missing spline style output shaft on the trans, you will have to find a yoke that matches.
