A club member put me in touch with a U joint expert in Ohio,
we have been working on all 3 types 30 mm and 28 mm are no problem
but the 24 mm are a little more fun.there is one for a mazda thats 51mm inside, we need 57mm and he can have them made but min. order is 500
This still will need a mod to the yokes but a simple one, If anyone else has found a cure or is working on it I need to Know , as there probably isn't even 250 axles of this type out there needing replacement.
