Jake, thank you for the offer, and if I can't locate another complete set, I will definitely consider the rear tins you have. I didn't think I would have such an issue locating the tins, but apparently these are a little more difficult to come by. If I can't locate a complete set, I will be in touch. Not many people piece out their complete tach dashes.
Thanks again Jake!
Tim, I think that's my other problem...

I haven't been able to locate an aftermarket supplier which will sell just the tins themselves, only a complete kit (lense, tach, harness, circuit panel, tins..). Whatever you can come up with Tim, post/email some pics and we'll see if we can work something out.
Thanks Tim!
