I'm no expert on this, but I know a couple of things.
The '92 cowl won't have the hole/mounts/whatever for the washer sprayers.
On the '92 the washer sprayers are clipped to the wiper arms and fed by rubber hoses.
I'm not sure if all the cowl mounting points are the same.
The hood latch mechanism may be different because the top of the core support on those two year models is very different.
I guess it is possible that the hoods themselves are the same and just have different hardware attached, but I don't know.
I wish I could give you more, but that's all I'm aware of.
