currently my 4bt has a ford setup on it with a t-19. what do i need to change in order to use a zf 5speed? what model/year bellhousing will work with my adapter plate the diesel or the 5.8 liter one and whats the difference? will my current t-19 clutch/flywheel work? basically what do i need to convert the t-19 to a zf with overdrive?
