IF you are short and/or skinny and you AND have flexible arms and remove any AC venting under the dash, it is possible to reach the twist off bulb holders without removing the cluster.

But if the cluster has never been out, it is likely that there is some corrosion that is best removed by pulling the cluster. Also with the cluster out, you can clean and re-paint the insides. Several threads on the subject.

Not unusual to have to bend the dash cover a bit to get it to clear things.

IIRC, by 79 they had switched to an electric sender oil gauge. My 75 cluster has a mechanical oil gauge with a small metal line to the engine block. But something to double check in case a PO swapped in an earlier cluster for some reason.

Watch for the green turn signal and blue brights small flat pieces of plastic. They like to wander off and can break fairly easy.
