OK,Dave y Im very interested in one and believe you when you say its top quality.It will be based on a modified quadrant you have supplied,yes???Can I ask you is this modified as per AP's website???Because I personally found that this mod makes the pedal sit way too high.I myself use a standard Mark 4 RST quadrant with the Mark 5 pedal,which when the bolt on the pedal is tightened up sit's at the perfect level,ie.. in line with the brake pedal.Sorry for all the questions,but Im sure you recognise all the different varients that have been mentioned on this Mark 5 pedal debate over the past few months.Best regards,Micky.
