Thanks for all of you ideas.
Since "persistent" is my middle name, John & I spent several hours yesterday running around the Pomona area (since we are here now) with Dave & Donna Fernandez, visiting a Napa Truck Parts warehouse, a Prevost service center and others. A big THANKS to Dave & Donna for spending so much time with us to try to solve this problem. Then, I made calls to Guaranty and all of the ex-WRV people I have contact info for. Burk came thru for me!!
The supplier for our 35 inch windshield wipers was/is Diesel Equipment Co. Their website is www.dieselequipment.com
. You can call 336-373-8331 and ask for Sean (who gave me permission to share this info), who will take care of ordering and shipping your big ole windshield wipers to your house!
