Here it is.
It is something I have done, and never gone back.
For a long time, I ran my shocks with internal limiting to keep the bone safely away from the edge of the outdrive, but I prefer more droop, and wanted to try a high gearbox - but this little problem stopped me from doing it. Then I put the BK2 axles on and it all fits great and now I can run plenty of droop, and more if I desire, plus space the gearbox higher.
Id recommend it.
