From what I've managed to find online, the dash is the same size and shape from '84 through '89. So my guess would be yes it'll fit. Question is, will it work though? If the wiring is the same I'd say yes. If not, you might possibly need the sending units from the donor car but I don't think that's the case here. From what I've seen online, 1988 also has the digital dash, does yours not? Or is yours just broken and you need a replacement? My instinct tells me this should work.
