How much difficulty did you guys have in removing the OE bolts? Was there any evidence of distortion in the OE bracket?
I'm going to assume (for the time being, at least) that the aftermarket brackets at least have the plates with the lower-side holes in them sitting in the same plane. Is there any chance that the car floors had become distorted (drag-race launches, wheel hop, etc.), which would make it more difficult to install the last bolt once the first two were in?
