Gotta love them German engineers. Last fall I decided it was way cheaper to get various and sundry parts on my bought-new '99 LT repainted rather than laying down 25 large for a new GTL. Both side saddle covers and the top trunk needed attention. To remove them I drilled out the rivets holding two pair of hinges in place on all three parts. After collecting up the now like-new pieces I grabbed my pop-rivet gun and kit of miscellaneous size rivets. Each of the six hinges require eight rivets, four per side, and each of the hinges are the same size. To minimize strain on the plastic covers, metal shims are used on both sides of the hinges. Rivets pass through the shims. The side saddle hinges popped on easy peasy. Reaching for the same size rivets, expecting them to fit the same hinges on the top trunk stopped me cold. They were too thin! I tried every size I had in my kit and nothing fit. So out comes my micrometer, and off I go to my local hardware store. Nope. Also nope at Loews and Home Depot. Finally I found them online where I had to special order a minimum of 100, with a price nearly doubled by shipping costs. The only explanation I can come up with is that the loveable BMW engineer who designed the side saddle never met the engineer who did the top trunk. Nice.
