60s used an "inverted T" setup like a jeep or most later straight axle fords. basically the drag link end fits in a tapered hole in the passenger side tie rod end.
i personally think it's a great idea for doing a crossover setup if you're too cheap to buy hysteer arms or don't have the clearance. since mini and FJ80 ends have the same taper, i'm fairly sure that the 60 ends would be the same as well.
the 60 box should work just fine as long as there's no problems with mounting it. they aren't widely used because they cost a lot more than IFS boxes.
