100 bucks a pair might be a deal breaker. i had a thought though...maybe i could use pipe and install the little push buttons in the pipe (push the button and slide into hole) if that is strong enough. that way they are adjustable, but i don't think i could make the tilt adjust that way...hmm. the two drivers of this car are the same size...maybe i'll just build them to fit one way and not worry about adjustment.
