Don't take this the wrong way, but I have built from the ground up many Lotus racing engines, suspensions, and transmissions in my earlier years for our racing team. I have never worked on AC, as it is not often found in Lotus 41's, Elans, Europa's built for racing. One uses these forums to educate oneself. If one cannot ask basic questions on a subject in a new field, then knowledge is not attainable, and the learning curve dies. It is not that this person is incapable of learning. I think once I have the information, I would be able to make the right choice as to weather I should proceed or not.

Kind Regards,

Geof
