Well it seems that the CPP "bug" may have bitten me.
I was going to install my new CPP modular drop spindles. I set them on the ball joint, and they're clearly not the right size. Both the upper and lower holes in the spindles are too large. I guess I'll be calling CPP tomorrow to remedy the situation (hopefully).
I'm guessing they sent me a set for a different year.
Additionally, the LS1 camaro brake calipers simply won't work with the stock size rotor
Now I have to find another set of calipers....grrrr
