Wanted 91 Camry hood stopper
#2
Try looking on eBay using the terms "hood bumper" or "hood edge cushion" ... I'm sure I've seen them there, OEM and cheaper than most dealers. You may have to buy more than one, though (example: 2 per pack).

Here is a link to a used two-pack on eBay that also fits a '91 Camry:
