I've had trouble finding diamante brakes, seems like every time one hits the junkyard the brakes are the first thing to go.
I ordered rebuilt ones for a 93 awd from o'reillys, and once I get everything swapped around I'll turn in my 90 calipers as a core, so I'd only be out 30$/caliper.

Not like they know the difference anyway, plus it helps to have friends at parts stores
