I am replacing the heater core on an 89 regular cab 4x4 DLX truck. I ordered what I thought was the correct connector pipe (hard pipe that fits into the heater core and runs to the bulkhead, see pic). Toyodiy says its not an applicable part, so I went off of what the toyota dealer said which looked right in the picture but.... The pipe I got (87156-35010) was too short and not bent correctly. Does anyone know the correct part number or aftermarket replacement? Thanks for the help.
