possibly. i know i'll be around the house doing stuff to get it ready for sale next month. depends if i'm free/in between projects but just shoot me a text. i'd verify from a local shop that you do have the replaceable Joints and not needing a complete shaft. if so, get the u-joints from Napa, not Vatozone.
all you do is remove the c-clips, then pop them out, since the cap is broke on one already, it wont be too hard to get out. get some 60grit and give the inside of the yokes a light scrape and the new one will slip right in.
It's staked though, so he'll have to cut the center section of the u joint out, push/press the bearing caps into the center to remove and then file and sand te stakes flush. Install new joint with with clips
