My truck did not have a coolant overflow or a windshield wash system.
I bought a coolant tank for < $10 from Walmart.com
I bought a windshield wash tank with pump for about $14 from amazon.
The coolant tank was good. The only issue was the input on it was 5/16 and the outlet on the radiator was 3/8. Here is a good summary on expansion vs overflow vs catch can tanks depending on what you want/need.

The windshield wash kit was a steal. It came with tank, pump, and a button to operate it.
