You can't re-orient the pulley because it is oriented by the hub, so it is the hub you have to move. The pulley only goes on one way. Obviously, you can't remove the bolts and spin the pulley to make the arrow where you want it and then bolt it back up.

one more thing, what if you cant tell which way it "was" on. My balancer has the 2 weights in it and I cant tell which way it was on!! I know, I know, I should have marked it but I was under the impression that it doesnt matter how it goes on. The t/c sprocket dots are lined up and I put the hub with the with the arrow pointed up, which should be no6 at TDC correct. I installed the balancer with the arrow lined up with the hub arrow, sound right. So tell me this, if i have any vibes can I just take the balancer off and spin it around one bolt hole and try it, or do i need to go 180 around.

If you put the hub on when the dots were lined up vertically, you are exactly correct.

Again, the pulley only goes one one way. You cannot "spin it around one bolt hole". The spokes on the hub and pulley are not symmetrical.

Damn, they look like the are the same, but if u say so i believe ya shoe, your the man. I must have got awful lucky when I put my pulley on cause i just lined the arrow on the pulley with the one on the hub and it went right on!! Maybe my luck is changing. My pcm came in today from Brain, all I gotta do now is adjust the valves and I'm ready to go
