What is the pedal box out ov, sorry ithrought it was a sierra pbox? in wich
case u could buy an HD off the shelf . trust me hydrolic is the way to go
i used 2 go trough cables every 3-4 weeks, so often i used to carry one in
the car. The WW master cilinders are only 115 mm long and u can
get them with remote resviours if space is tight.
