We'll I'm a day late but here are the part numbers.
KYOPZ002 kyosho steering block set. (Has the football)
KYOPZ012 kyosho 5mm pivot ball ( I used them on the links also just incase the ball height was different than associated)
KYOPZ040 kyosho pivot nut & ball seat
I am 90 percent sure that is all that is needed. I also screwed up and ordered KYOPZ004 but I'm pretty sure I didn't use anything from it. However now I'm wondering if the side lengths are the same length as Associated? Maybe time to get the calipers out? If they are different I wonder what effect the length of the side link has? Just might be reason for more testing!
