Radiator pressure test kit question

[JMBT]

Thanks Hammerhead, I will determine which of those two Volvo numbers is mine. My brother's KW has the old style metal top tank, may be closer to your 97 pete. I'll have to do a bit of research on that too. I remembered earlier, he had this current Radiator custom built 6 core for heavy haul, so it may not even be the regular 99 W9 setup.
