Beagler, you have posted asking for advice & recommendations which several people, who have considerable experience in this field, have kindly offered. However the tone and attitude of your replies is somewhat disparaging and unnecessary IMO. We are a friendly club with a membership who collectively have considerable knowledge of all things Caterham & Lotus 7, members that are more than to willing to help. Perhaps a bit of courtesy wouldn’t go amiss, after all it costs nothing.
