Do you have any diagrams or pictures of how you put this together. I'm working on a gauge cluster set up and getting a little frustrated.
I have a another pic of the back side after wiring, I can post up later when I'm home. Mine uses a blank flat panel that a guy was selling on eBay a year ago. He supposedly had a mold made and maybe a dozen panels made that he sold. After keeping a couple panels for himself he was going to sell the mold so someone might start making them again. Your wiring will be different than what's in my '70. Even the diagrams I found on line didn't match my car. What kind of problems are you having? PM me if you want, that way we don't hijack this thread.
Don't pay too close attention to the voltmeter in the lower right corner, it was wired wrong when I took the photo. LOL
