Does anyone have or know where to find the complete arm with all the screws and covers for the windshield wipers?

Basically, my windshield wipers started acting up and I took them off to try and find a problem. I set them on the hood and got sidetracked. My brother did not know and used my car to run some errands. I did not return to the car till later the next day to realize they had gone missing. The wipers fell off when he took out the car, and we can not find them for the life of us. I know it's ridiculous, but I really just need to find some wipers as I use the Montero pretty often.

If anyone is parting out a 1990 Montero or just has some sitting around I'd love to take them off your hands. Any help is always appreciated! Thanks!
