Where can I buy pedal extensions for our car?

I am taking my knowledge test tomorrow, and hopefully will get my permit. Although, I won't be able to drive unless I can find pedal extensions for one of my parents cars. I'm 4' 9" and I can't reach the pedals and see clearly unless I am really close to the steering wheel, which has an airbag. My parents don't want me to be there, which I understand. They don't really want to get me my own car until I have my license. I have called auto parts stores, contacted the Toyota dealer, and no one sells brake/gas pedal extensions. They tells us to Google them and buy online. Ok, I've tried that too. There are so few online and they aren't for Toyota. (My parents have a Toyota Highlander- 200? and a Toyota Camry-1998) We are getting so frusterated. My drivers ed teacher acted like it would be easy to find them, but it isn't. We live in Minnesota. If someone could give me/us info on where to find some (preferably locally or online locally) that would be wonderful. Thank you!! :)
