Try CE-DFW in texas especially for Toyota, Cat, Mitsubishi. www.ce-dfw.com also try looking on slparts.net
The state of Texas has a program that pays end users to retire old units and buy new ones. The catch is they must cut the frame and cut a hole in the block to make sure the unit never runs again. This leaves a large number of salvage trucks that have many good parts to sell. Texas is a great place to look for used parts. Good Luck
