Just adding my 2cents....

When I needed to replace the CVs on my '85, ;I pulled the shaft, found
out that the FLAPS didn't have stock on a rebuilt half shaft.  He had
mine rebuilt for $100, which was less than it cost to have the mechanic
replace the boot.  Moral - your local NAPA dealer may be able to get
your drive shaft overhauled for a great price!

(Yes I know it may not be 'german CV joints', but they worked just
fine....
