I've decoded most of my build sheet, but need some info from the experts here:

1) Below the "11" row (the last row), there is a stamped #13 followed by "Oil Unit." What does this mean?

2) What do the W11 "Deluxe 14" Wheel Covers" look like? Can someone post a pic?

3) What was the code for the rear window defroster. My car definitely came with one from the factory, but I don't see it listed on the build sheet. The column is there ("H" on row "6"), but there are no markings there.

4) Where do the M25 "Wide Sill Mouldings" go, on the top of the door? Looks like my car did not come with them if they go on top of the door, but the Broadcast Sheet says it did.
