Have you validated the model number at an online parts site like Repair Clinic? (yes or no): Yes

Have you watched the video on how to search for manuals and have you searched the Downloads section prior to posting this request? (yes or no): Yes

My parts distributors do not show this model. I can sub the 3 in SJ3SS with 4 but still do not find a main CBA.
