My 89 convertible came back from the painters with these in the boot. Does anyone know where they go??? Thanks

 

For a start, they look like Slide-In brackets. And the one has a wiring clip too. We could use a size reference. How big are they? Did they send any bolts with washers back for better reference? As clean as they are, I would suggest they were not under the hood or outside. Most likely in the trunk. Maybe fuel filter or the wiring near it? Just my guesses....
