You know those nights you just can't get to sleep because that project won't leave your brain? That's tonight.
I've got an '85 Trans Am that I replaced the steering gear in about a year ago. Only after replacing it and returning the old one for the core did I learn that there were stock and performance gears. I don't know which the car came with and it was too late to check. Stickers are all missing.
So, after the replacement I realized my tires would rub the frame when locked either left or right.
My question is this: Did I get the wrong steering gear when I replaced it, and is there a way to stop it from rubbing?
Also, I assumed when taking everything apart that the flats in the splines would keep everything aligned when I put it back together, but my wheel is now tipped slightly left when driving straight. Is this related to the steering gear, or was I just stupid and misaligned the shafts when I put everything back together?

Any responses are appreciated, even if it's just telling me I made rash maintenance decisions.
