I don't see any difference in gauges except 56 temp says "C" "H", cold is still "0" on 47 gauge and 220 is definitely hot. The 47 cluster should work just fine. Two issues to remember: 1. Gas gauge needs a voltage reducer. 2. Need to investigate sending for temp and oil. Mechanical vs. Electrical vs 47 vs 55/56
