If you are looking for a pillar pod to fit the Millenia look no further than an RX-7 from the same age. In my brothers 95 we installed a pod from the mid 90's RX-7.

It of coarse fits the normal 2" guages. So if your looking for extra space for a air/fuel meter or boost for your Millenia S or what ever, these look real nice.

They are made by Auto Meter and can be ordered from just about anywhere.
