Are all Spit U Joints the Same?

["Kirk Crawford" <kirk.crawford@home.com>]

I suspect one of my U Joints is bad on my 68 spit.  (it clunks when putting on
or taking off power)  Before I go looking for a replacement I have a question
for the list.  Are all spitfire U joints the same for all years?

Thanks in advance,
