I finally got around to upgrading and installing new headlights on my LX. You can scroll through the gallery below, or click on the gallery to view the whole thing on Imgur.

Wow. The Lutz Auto speedo calibration is simple and easy.
Before I started I collected four data points (50mph, 60mph, 65mph, and 70mph) and calculated the results. I then averaged the four data points for a -.07% for my final calculation...
I've got a yellow box sitting in my parts drawer. I installed it once but it did not change the speedo. Not long after that I had battery problems (bad alternator) and removed the yellow box during troubleshooting.
I came across this thread...
I ended up putting this kit online at the link below. Thanks for all of the support:

Sometimes the standard USPS shipping is very slow to Australia. The more expensive shipping options will get it there in a couple days, but they're pretty pricey for one item.
