Mirrors....I got the idea from Kahuna (Autozone mirros with velcro), and primarily use them to maintain eye contact with passengers. Very useful to make sure they are still with you and not turning green...
Pedal extensions .... I just looked at pictures (I think they were from Randy Lervold's RV-8 site) and copied them - plans not required.

Yes there are blind spots you can buy at any autoparts. What I am looking for were shaped to follow the roll bar on the inside of the canopy and were used for formation. I have also seen these in some military planes. There was a vender ad here at one time.
I would like to have for number of reasons. In the rv7 your view is block behind you. I would like them for taxing, formation, parking.
