have a np203 with a ujoint type mounting for the drive shaft(203 is shot) have a replacement np203 but it has a 4 bolt flange for a shaft hook up, are they interchangeable ? /forums/images/graemlins/1zhelp.gif
Some are, some aren't. Just pull the yokes off and if the spline count is the same then you can swap them. Some are like 27 spline and some are 10 spline.
