fuel injection wire harness heat shield

I have a 2000 Tacoma 3.4L V6 and I removed the fuel injectors this weekend to have them professionally cleaned. In the process of getting to them, due to the high temperatures and the age of the truck, the plastic heat shield that encases the wire harness for the fuel injectors cracked into pieces. I cannot find this plastic heat shield anywhere and the only way I think I can get one is to purchase the entire wire harness and that will put me out close to $1,000. There is nothing wrong with my current wire harness and I was wondering if anyone here knew of a place I could get one.

I have checked local salvage yards and nobody here has a Tacoma in their yard. I am sure most of the heat shields in a salvage yard are pretty much in the same condition as mine.
