Need some help

Hey guys i need help installing my under drive pulley back on my car. My brother pulled it off and didn't mark how it went back on, I put it back on but i get vibrations when my RPMs get to around 3000 and higher, i dont know if its caused by the pulley not installed right. Any ideas?

I cleaned around the area where the pulley was going to mount on the crank. then I just pushed it into place making sure it was lined up with the holes for my bolts.

Sorry I didn't noticed that this was on an LT

They are a bit diffirent than a LS...Only thing that I could think of is (may be a pain in the ***) but put the stock 1 back on and see if the vibration goes away...

Well i put the stock pulley back on and still has the vibration. I belive its coming from my trany. A couple of days ago i broke my third rear trany mount this year. So this time i bought the Energy Suspension rear trany mount instead of the cheap Auto Zone i was buying. Could this be normal
vibrations from using a firmer rear trany mount? Thanks

Yeah thats where i think its coming from. I guess i just have to live with it unless i can find something better that will not cause any vibrations. Any ideas?
