Mark, Those Knucks are an odd bird. They have a really long steering arm that requires a really long pitman to get full turning. They are not compatible with d44 high steer arms but they do have a taller placement of the tie rod. You can use chevy outer hubs on those scout spindles. When I was wheeling scouts I drilled the 8 bolt pattern in in several gm spindles cause scout stuff could not be had in a pinch. I probly have one or 2 still if you need em.
I would assemble what you have best you can and use it while searching for a chevy d44 with flat top knucks. I have lots of outer chevy stuff I can ship ya if you need it.

Good thing I am using the Scout steering box too.
