I don't know of any CV lasting over 50,000 miles from the 1980s, even if you had a Toyota.
My '85 Nissan made 130k miles, my '86 Vauxhall managed 127k one side, the other still good when it was scrapped at 180+k miles, my '86 Olds 88 still good at 150k, my '89 Buick Le Sabre at similar mileage also still on original driveshafts, to be fair it has has two replacement boots.
Even back in the '60s CV joints regularly saw out the life of the car without failure. I owned a few British FWD cars back in the day, whatever their many other failings, CV joints were mostly trouble free.
Claud.
