Single part number? Try about 19, not including the hardtop and attached seals (see below).
I have been slowly piecing together all the bits I need since buying the hardtop on its own. I got the expensive trimpanel and side covers on the forum, storage bag on eBay and went to Lotusgarage.com for the rest.
