Yeah, you need to drill out the outdrives using a 6mm bit. Additional clearance is needed so the ball on the end of the dog bone can pivot freely.
Also, you need to shave about 1mm off the section where the bearing pushes over the diff case on both sides so they sit further towards the centre.
That's it! Easy to fit.
