Ok as i said i have done a search on this and i cant really find out what i need to do i have some idea like the control arms and stuff. Can these be swapped over do they unbolt or do i have to weld them. What else needs to be done, or can it be done? Thanks

Just doing a bit of reading if i swap to the 9 inch i would lose ABS? would i have to get new axles to keep it can you get abs axles for 9 inchs.
