Will BJ4 rear CVD's fit in a B44

[super79a]

Will BJ4 rear CVD's fit in a B44. I am having major problems with dirt jaming up the factory CVA's, so I was wondering if the BJ4 CVD's will fit. I have Factory Team B4 and T4 and have no problem with there CVD's. I drive on a very loamy track which creates large amounts of dust. I even get dust under the rear ball cups on the B44, even when I replace the seals often.
