Best Racing Clutch?

Got my Lotus 41 out of mothballs and drove it for the first time in >forty-three years at the GGLC trackday this past Tuesday. The clutch >was misbehaving making horrible chattering noises and only partially >disengaging. 

After that length of storage you may just have surface rust on the splines of the gearbox input shaft. The friction plate needs to be able to move smoothly along this to disengage cleanly. Similarly if it has a sprung centre then this may have siezed, the chattering could be loose centre springs.

The car was stored in a very low humidity environment, there wasn't any rust on the brake rotors so I doubt that is an issue. Other members of my family have complained about how it did not actuate very well and now I got to experience it firsthand. It's going to be replaced with a better solution. Pretty sure it did not need the dual plates with amount of torque this engine puts out. Here's what the plates look like. The clutch unit is an older now obsolete style. http://www.tiltonracing.com/content.php?page=list2&id=403&m=d-Keith 

I'm also looking for a Standard rear axle for a Series 2 Seven. What is the difference between the wagon and sedan axles? Did I not read that Sevens built in some time frame used Austin/Nash Metropolitan rear axles? If so, were these modified to the 3.75" PCD?
