Quick take
When a camera is already open on your bench, the missing part is the whole decision. These four camera repair parts cover two different repair paths: Nikon D-series spares and Leica rangefinder spares.
The Nikon side has a new aperture motor gear named for the D80, D90, D60, and D70, plus a used D5100 body-cover set that includes a 3-inch vari-angle LCD monitor. The Leica side has two single-piece Leitz Leica spares, one with the part number 042 216 000 112 and one listed without that number.

Product notes
Replacement Parts Fit For Nikon D80 D90D60D70 Camera Aperture Motor Gear

Keep this on the list when the aperture motor gear is the specific Nikon part you are replacing. The title names four compatible bodies - D80, D90, D60, and D70 - and the condition is listed as new. The description says 100% brand new and high quality, and it mentions a 30-day warranty from the purchase date. At USD 8.45, it sits in the middle of this four-part group. The limitation is price relative to purpose: it is not the cheapest piece here, so it makes sense when the gear is the known fault rather than a first guess.
Nikon D5100 Digital Camera Replacement Parts with 3-Inch Vari-Angle LCD Monitor

This is the only part in the four-product group that includes a screen, and it is the only one named for the D5100. It is listed as used, with a price of USD 14.78, and the description says the parts came from a Nikon D5100 and include the front/rear cover plus a 3-inch vari-angle LCD monitor. A 30-day warranty is also part of the listing. The limitation is scope: the description says body-only, with no lens and no other parts, so it addresses shell and monitor work, not a full camera rebuild.
Leitz Leica Rangefinder Camera Replacement Parts x 1 piece 042 216 000 112

This single piece is the lowest-listed-price option in the comparison at USD 8.00. The title is specific: Leitz Leica, one piece, and part number 042 216 000 112. The condition is listed as open box, while the description says new and never on a camera, so the two parts of the listing do not line up perfectly. The design is listed as round and the origin as Germany. If your repair matches that part number, this is the spare to start with; if the part number is not relevant, the other Leica listing is the general fallback.
Leitz Leica Rangefinder Camera Replacement Parts

The second Leica listing is priced at USD 9.00, one dollar more than the numbered single piece. It shares the Leitz Leica brand, open-box condition, round design, and Germany origin with the other Leica part. The title difference is that this listing does not include the 042 216 000 112 part number, so it reads as the general single-piece Leica option. That makes it the one to choose when you already know a round Leica spare is needed and the part number in the first Leica listing is not the one your camera requires.
