Hi, Can you please post where you sourced the Cologne bell housing for the mazda 5 speed and what it came from? I think I need the same one... I have a 1987 B2600 4x4 with the mazda 5 speed manual that I am interested in putting the 4.0L in. I was going to go with a mustang 5.0L but not sure if I would be able to retain my manual trans. The 4.0L sounds like an easier conversion. Any info on this swap would be greatly appreciated!
