The u joint i swear by is the DMI with the alum base and the lightened steel slip yoke. i have been running it exclusively for about 7 years, ever since my last sander yoke exploded between my feet taking the torque ball with it. it is plenty small to fit in the midget tube and is really a nice peice. the first one i bought is still in use in car i sold a few years back. it has never had a problem and is in its 7 season of use.

I had to give up on the alum. slip yokes after splitting two in one season. i'm no engineer but it was my opinion that the four cylinder harmonics, especially when pushing off were too much for the alum joint. i think they say it comes out about a 1/4 lbs. heavier than the all alum. and use to be less expensive. not a bad trade off for the reliablity you gain.
