Rob,
as Chris already typed there is only one type of hardtop, which received small changes during production of the W113. First the 1-part locking handles on the 230SL changed to 2-part removable handles on the 280SL, rails for a roof top carrier could be added and finally a heated rear window.
What you received from MB Classic is only half of a 2-page parts display in the 230SL spare parts list (see attachment). What SLS did was to combine both panels into one and add the parts that differ for the 280SL hardtop and also change the numbering to the most recent drawing in the catalog. That is, when you think that numbers 86 & 87 "do not appear on Type 2" it is because you only received half of the drawing. They are numbers 25 & 26 in what you would call Type 2.
You typed
"It certainly won't help me source parts #85 and #86 -". However, if you click on #85 on the SLS graphic a new window opens telling you that it is Mercedes part number A11337950185 or A11337950285 for the left or right trim piece, respectively. If you click on #86 then MB part numbers A1137950585/0685 show up.
You can use these part numbers to order yours, and remember odd number are on the "left" and even numbers are on the "right" on LHD cars. Fortunately, the part numbers are the same for your RHD cars.
