Excellent point. CV joints were stock on the stronger ZF 'Super-diffs' used 
after 1980 on BMW M-1s and a few other sportscars. I'm not sure they're 
strong enough to cope with total neglect in greasing though. Last time I talked 
to Lloyd Butfoy, he had a few of the late model inner/outer stub axles and 
matching halfshafts that use CV joints. The conversion would not be cheap 
but once done it would be lighter and much neater than steel adapters needed 
to run CVs on early halfshafts and stub axles. I've seen a couple of 
conversions- one using BMW 735 CV parts and one using Porsche CVs. Welding is 
required for changing the halfshaft ends, with fabricated adapters on the inner & 
outer stub axles. Haven't seen Byars conversion yet; if anyone has god 
photos, I'll run them in the POCA News. Thanks- J Deryke
