And a link to Justin1600 C43 Project thread, the entire thread is well worth a read, but he starts mentioning the DD conversion on Page 25 of the thread, post 364,

I thought I remembered another thread in the HOW TO section of the forum regarding fitting an early COMMAND system in a 202 (COMMAND is still a DD so is applicable even if you don,t fit OEM COMMAND), below is a link to it.
It is very old one of the earliest in the section Sept. 2003, but it has loads of pics which are still viewable and deals in quite good detail how to take the car apart and modifications and parts required.
