anyone ever use these u-joints

[SuperDutyScaler]

first run out my son blew his u-joint's today. I haven't bout any axial or traxxas metal ujoints in at least three years andman have they went through the roof! So looking on Tower Hobbies i found these for a Traxxas villian, problem is they dont list the shaft size or wether they work with the standard traxxis plastic driveshafts.So anyone use um before? i guess for 4 dollars ican just take a chance.

I'm pretty sure the boat drives are only 4mm So those would be pretty small openings.

It looks like 4mm is correct, here's the link right from your page for the shafts that go to those
