Well, I think that I might do the same with the carpet and bed liner as you did. I don't think I need access panels though. I have a SB302. What shape of foot rest did you install? I'm picturing a horseshoe in my mind, to block heal movement forward and sideways. Any issues in that, say moving right foot over to apply brake pedal? I have not driven any Cobras yet, so not sure about what items need to be addressed. Thanks for your help.
