U-Joints are easy to replace , as long as you can get in under the car.... I did my first set in 1969 on a 67 Mustang ,I just failed to make sure they were in right before I test drove....they snapped , and made several chunks of concrete come out of the drive way , plus made for less foot room in the back, where the drive shaft also dented the floor board from below... like mentioned above , it was a lot easier to make it right the second time....
