I decided the purchase the anti skid regulator from Beringer (ALIR). The recommendation is to install below the middle pedal bearing. Unfortunately the support provided by Beringer works only if the pedals are mounted in the most rear position. As i am 1,83 cm tall, i prefer to install the pedals as indicated in the plans in the most forward position.
I tried to position the ALIR regulator on the left side, below the pedal bearing as indicated by other builders, however operating the regulator was impossible for me.
I resolved creating a new support. First try with a 3mm aluminum, but the result was not satisfactory. I used a normal 2mm aluminum and i am pretty happy with the result. Especially considering that my band saw is broken and every attempt to repair miserably failed.
I test installed before priming and painting. Final install still to be done.
There is enough clearence from the firewall and from the aluminum brake lines.
