Some time back I installed an Autometer 10K tachometer in my 68 non-tachometer cluster (where the fuel/volt and gas gauge goes), the gas gauge was relocated to center hole where the optional clock is installed, and a different volt meter would need to be installed separately or not at all. I made new faces for the gas gauge and the tachometer so they matched. It turned out pretty good (I may have a picture around here somewhere), and I always planned on making a kit, but haven’t got back to it in some time.
A few things of note off the top of my head: It’s less expensive than an aftermarket cluster, and gets you a 10K tachometer that looks stock. However, you lose one gauge (voltage in my case), the needle on the Autometer gauge does not exactly match the other needles (but can be painted to match the color, but the shape is a bit different), the gas gauge is an “upsweeping” gauge, while the other two at the top are “downsweeping”, and you have to remove the little blue bulb covers inside the cluster.
I made templates for modifying your cluster and everything, but ran into an issue or two in providing a quality mount for the gas gauge (it won’t simply bolt in on its own). If I thought there was great interest in this, I’d get back on it.
Coincidently, I just received a “private message” from a guy here asking about this kit. I need to get back to him…
