The coolant overflow tank can be an aftermarket option or the OEM option the most important thing though is you want to make sure you keep the overflow tank close to the OEM seize. I went with a 1.5qt overflow tank. Because I am not using the radiators overflow nipple, I routed the overflow from the expansion tank to the bottom of my overflow tank.  I am using an Ebay aluminum overflow tank plenty  of options available I went with one in black.
