Coolant test strips

[99' Powerstroke]

Where can I buy the coolant test strips? The ford dealer said they don't sell them, and I called an IH dealer and they said they don't sell them. Napa just had some testers that looked like a kids science experiment and wasn't sure if they would work on my truck. Do these test strips just test the water to coolant ratio or do they also tell you if you have enough additive in there too? Are they diesel specific?

I think Black Cloud sells them as well as Powerstrokeshop.com, but talk to someone else at IH they probably have them in the back and the idiot you talked to didn't know what you were talking about.
