I bought a 3.4" pully from ZZ performance and also their pully instal/remove tool. It took me a bit of effort to get the stock pully off, but when I while trying to put the new pully on, I broke both of the smaller bolts that go into my nose drive before I could get the pully all the way on. I kept the belt off and took the car to a local shop, where they also broke 2 tools trying to put it on. The pully never got fully on, and now I think the threads inside my nose drive are stripped.

I'm pretty lost what to do now.
