Just wondering where I can get replacement advance springs for the above distributor.

Also what grease is used internally.

Some details are in an old post:

viewtopic.php?f=2&t=63023&hilit=factory+cooper+S+distributor+advance+curve&start=0

The original springset for Mk2, according to winabbey's research, is Lucas 62411108.

Thanks Bill B. Have done a Google search and come up with nothing.

Given the lack of spares and the high price of that which is available for 29D's would you be better off with a different model?

The springs should be interchangeable with the 25D, and you can use nearly any brand of distributor springs as long as they give the right curve

You might be better off to get a custom curve put in your distributor to match todays fuel and the spec of your engine. Even brand new, the Cooper S was reported to have pinking and the manual asked you to change the base timing pending on the fuel you used

Being an Australian distributor 'distributor doctor' had nothing for me.

Springs are springs, as long as they are the right length and strength

So what is needed right spring dimensions for this distributor.

You need the right springs for your engine and modern fuel. As mentioned above this might not be the same as from the factory

Any decent distributor shop can graph the curve and adjust it to be correct with the vast selection of springs they have
