Mike,
Info from shipping list:
Valves: 61-5-0, Stem and bonnet assembly, Valterra P/N, PR187020
Handles: 6-38-9-16HC, Handle set large bagged, Valterra P/N, PF187042

The assembly for the diverter probably has a different P/N than the one above for the valves. The 61-5-0 number listed above was the one inscribed on the valve assembly. The diverter assembly should also have a #on it.
The customer service rep at Valterra was very helpful. They are located in Mission Hills, CA so Pacific Time Zone.
Good luck,
John
