Some suspension and brake questions

OP will still need to get 73 up Disc brake lower ball joints and grade 8 bolts for the swap. You can use these bolts to do this. Get grade 8 and "stove nuts" dimension shown is a bit long. They could stand to be 1/8" to 1/4" shorter than what's shown in my screen shot. You will need 2 per spindle to attach them to the lower ball joint.
