On my 300D 83 model the fuel gauge is erratic and the reserve light comes on between half & a quarter tank of fuel. I have not diagnosed the problem yet, but I suspect the dash unit. My question is can you replace just the fuel gauge portion of that gauge cluster or do you have to buy the whole gauge assembly? I suspect that the whole assembly is rather pricey!Any help would be hepful.One other thing would this be available through the part's shop section of this site?
