Not to bring this thread back from the dead, but I am assuming that these will snap into the back of the speedometer nicely? I finally got mine put back together, after realizing I made a mistake doing it the first time, and when I put the gauge back in the dash, one of the bulbs stays in, the rest just pop back out. On the upside, the fuel gauge works now, and once I get the bulbs in, I'll find out if the speedo works too. I did order a handful of them, so hopefully they will work better than the old tired OEM sockets.
