the 10 will fit change the bearings with BDX bearring kit or just buy new bdx gears you can clean dd and swap 05/06 and 09/10 dd gears in less than 45min.IMHO I would not buy a used DD unless you know the sled it is out of and you know it has low MI .I swap plannitarys at 1200 mi just to be safe with bdx planitarys only way to go.or else a bdx lite drive that is what I have they are sweet you have a dip stick to check oil condition and what not only bad part of bdx light drive is you also have to swap drivers.but a good DD will pay for 1/2 the cost of a BDX light drive
