It would help if you post year and model!
Now if you have a 70 series then a longer C.V.(birfield) is what you want.
The newer 80 series C.V. will fit.
If you have part-time or electric hubs you can convert that side to functional by removing the parts and simply add a drive flange of the appropriate thickness.
Note my 75series...one part-time hub on drivers side, full-time on passenger side.
The 79 series will fit, But you need to file or machine the top outer splines to fit the drive flange.
