Hi, over time I have collected several working components of the 123 gauge clusters...I have been experimenting with ways to make the illumination lighting better on my wife's '82 300TD.
Anyway...I have two suggestions for you.
1. Unless for some reason you need and really want the entire cluster, why don't you buy the component you really need and change it out yourself. It's very straightforward.
2. Depending on the urgency, you may have heard about the Pick n Pull recyclers out here in Clifornia. Quite reasonable prices and they even have half-price days a couple times a year. The 123 clusters are out here in abundance ( I'm sure that's what you wanted to hear, right!) and if you could be patient, I will be going next time there is a half price day and I'd be happy to pick one up...your cost would be the price I pay plus postage.
