the only thing that really needs to be removed before the cluster comes out far enough to get a look in there is the speedo cable - the oil pressure gauge fitting may also restrict movement, but usually with care you can pull the cluster out far enough to get at that, or disconnect it from the engine so it can pull thru the firewall
