I have a question, I just did the z31 pentagon hub swap with the JSK rotor hats and Wilwood calipers. I swapped out all the bearings and seats along with the seals. When I pieced everything together and put it on the spindle, the z31 hub doesn't slide in all the way. I have about a 1/4 o 1/8 gap. I installed everything correctly i am sure of it because its the gap is the same on both sides. Can anyone verify if this is correct?
