morning, i just took out all the hollow balls out of the front and rear turnbuckles and camber links, to give them a clean and put them back into my new green rpm rod ends, but ive just noticed out of all the hollow balls 2 are not flanged on one end, i thought all the hollow balls were suppose to be flanged...? so my question is where do these 2 non flanged hollow balls come from? as on the exploded views it does not say.....
