underdrive install
https://ls1tech.com/forums/tools-fab...tool-pics.html
I just finished mine tonight. I went to pep boys and got a 3 arm pulley puller. Autozone's free tool was wrong. I had to just take a flat block of wood and kept hitting the pulley with short strokes till it moved enough for the bolt to grab. Autozones tool was supposed to work for the install also but it was also wrong. So that's why I used the wood. This is the style pulley I got at pep boys

I highly recommend getting a new bolt and installing it properly (torque to yield process) after the pulley is fully seated.
