FILTHXR6

I have a 2003 ba xr6 turbo with a 5 speed gearbox, wanting to put in a 6 speed. I have found a fg xr8 6 speed gearbox. Can I use the bell housing from my 5 speed on the 6 speed gearbox? Will I need to buy different tail shaft? Please let me know of any other things I need to do for this gearbox change. Thanks
