Ok, thanks...I think that I'm going to try and use that. My heap isn't original anyways and it goes up to 120 instead of 110. I've got a 65 cluster also for more parts. Well, you wouldn't have an extra fuel gauge from a 66 would you. If they fit easy enough in the 64 cluster dish/box or what ever it's called. I'll send them all off to get refurbished. The trip meter is neat feature.
