I have a '93 LX Auto that may (or may not) have the original cluster. I am looking for a resource that has the correct cluster for this car and acceptable replacements. The installed cluster was part #78100-A500 and has SM4 and A04 stamped on the label. This cluster is not a DENSO Potential replacements that I have: A Denso produced cluster which appears to have the same configuration, part number 78100-SM4 and the next line has A571-M2 A cluster with part 78100-A500 and stamped SM4 and D04 but has the yellow "55" on the speedo, no SRS light but with a "S" indicator light below the temp gauge. Thanks in advance for any help!
