Looks like it is for the 81-89 F FT600/800,FT900 medium duty trucks. I say that because the ID# ends in "B" but has the extra "A" elsewhere, so that makes me think it is E1TF 10C956-BA, which fits with the ammeter, tach, and oil pressure gauges.
However, I don't know what the LED's are for. At first I thought it was actually a picture of my cluster that has an Edelbrock AFR meter in that spot. But it isn't, and I don't know what those are.
