If I had to guess, the bolster is attached to the lower panel with screws or something like that, so removing it will leave holes behind. Could someone not in the US find out the different part numbers for the different color lower dash panels from their local dealers for us US drivers? I would really really like to get a panel that does not have the bolster. My upper shin grazes that bolster while depressing the clutch at times, so not having one would make the car a LOT more comfortable.
