It hasn’t been stated or asked.
Does that bell have a 4 + 11/16” center bore. If it’s bigger than that you will need a spacer ring to downsize the hole to 4 + 11/16”.
Does the intended T5 have a SaginawMuncie bolt pattern?
In the USA, a Ford bolt pattern was used in the T5:
1993 and newer Camaro/Firebirds
1994 and newer S10/Sonomas
and of course in all Ford Mustangs.
Video explaining some of this.
