Not to mention the Scout front 44 is a poor choice due to 0º caster, you'd have to have the knuckles cut, rotated, and welded to have proper handling.
Take a look at a Waggy front and rear D44 from late '80s or '90s, or a Waggy front D44 and an Isuzu rear D44, this will give you matching 6-lug axles and 4whl disc brakes.
