I am interested in seeing how this works out. I have a 63 that has the original rear and 17 spline axles. I am getting ready to purchase a posi which I can only find for I think 30 spline axles which I think is the '65 and up. I will probably end up getting a set of 6 lug 30 spline axles from Moser or another supplier. I am also buying the install kit which has the shims, bearings, and seals. My understanding is all the 63 to mid '70 when they changed from 6 lug to 5 lug are the same housing and axle length with the exception of the 63 and 64 axles had 17 splines and in 65, they went to 30 spline. I will be curious to see what people think or have experienced before I buy the install kit.
