Inner fender or something rubbing firewall. On my LS swap my coil bracket off valvecover was rubbing and made a terrible chirp on passanger side. My other annoying squeak that took a wile to diagnose was my steering column to dash bushing. THAT one drove me crazzy.
I would love to get more detail of this for I'm having a chirpy sound coming from my steering column (I think) as well. Were the two bolts that hold the steering column to the dash just loose?
