Old 2,0 4cyl has same bellhousing pattern than 5cylinder engines. FW bolt pattern seems to be 6 bolts, but M12 instead of M10 used in later 4cyl. No idea how close itīs to later 4cyl.
someone tried to buy my audi 2.0 diesel off me for their mail jeep recently actually. for all i know it could have been the OP.
