[DeTomaso] stock halfshaft u joint

[Justin Greisberg]

what fails when the shafts fail?  What part actually breaks?
i installed new u joints from Pantera East in florida a few years back -  they were a little long in one dimension but I mostly got the original clips to fit in place.  However, one of the end caps was not too tight in one of the u joint "holders" on one end of one halfshaft - the press fit was not so tight anymore.  no free play, just not too hard to slip in.    all the other end caps were tight everywhere else, and required a vice/press to install.  i dont think this would be likely to cause a failure - but asking?
