I doubt you are going to find any new tooling for your machine. Therefore you will need to make it yourself. Various supply stores such as MSC or McMaster will offer a ⁵⁄₁₆/.3125 HSS blank that you will use to make you own cutters. I think they are about $10 a stick and they are about 5 inches long. You will need to machine a vertical groove/relief with a ¹⁄₃₂ ball end mill for the set screw ball to center to. Then grind and shape the tool for the profile of cutter you desire.
As for the cutter for the thrust, I have never used one of those types, and it appears to be too large to get in there anyway. You likely will need to grind your own cutter for that too. That way it can be adjusted to only cut in the pocketed area. I am not sure what you will use to tension the bar there either. I know the KW has two adjuster feed screws that clamp against the bar and then push against a main webbing to tension the cutter against the main web or cap.
