Hey guys looking for a little help. I bought some used extended arms of a guy that said he had them on his blaster. I think I got what side what one goes on. Is there any easy way to tell? I don't remember who makes them I will have to look when I get home. But my main question is when I am trying to put the a-arm ball joints into the hubs the ball joint pin is bigger than the hub hole. I know they are tapered from the factory but this is not even close. Is this normal? For u guys that have extended arms did u have to drill the hubs larger? Please let me know any help would be great. Thanks.
